October 31, 2012: The regular season for the Suns begins.
January 18, 2013: Coach Alvin Gentry ended up resigning from head coaching duties.
January 20, 2013: Lindsey Hunter is announced as the new interim head coach for the Suns; assistant coach Sean Rooks resigns from his coaching duties.
January 21, 2013: Assistant head coach and Suns fan favorite Dan Majerle resigns from his assistant head coaching duties; Phoenix Mercury head coach Corey Gaines becomes assistant head coach for the rest of the season.
January 23, 2013: Defensive assistant head coach Elston Turner resigns from his assistant head coaching duties; former Phoenix Suns scout and Shanghai Sharks head coach Dan Panaggio becomes assistant head coach for the rest of the season.
On July 3, 2012, Eric Gordon agreed to a tentative deal with the Suns for 4 years and $58 million. However, despite Gordon saying that "Phoenix is where my heart is now", since Gordon's a restricted free agent, his offer was matched by the New Orleans Hornets a full three days after signing free agents officially took place. Phoenix has, however, gained both former back-up point guard Goran Dragić and forward Michael Beasley as of July 4, 2012. As for Steve Nash, he was officially traded to the rival Los Angeles Lakers in exchange for first and second round draft picks in the 2013 draft, as well as a first round pick in the 2015 draft and a second round pick in the 2014 draft on July 4 as well. Grant Hill also went to Los Angeles, but he went to play for the Los Angeles Clippers on July 18, 2012. Ronnie Price would sign with the Portland Trail Blazers on July 18 as well; however, unlike Grant Hill, Ronnie Price would be waived by Portland on February 21, 2013. Aaron Brooks would go to the Sacramento Kings on July 16, 2012, but he would play for them until March 1, 2013. Four days later, Brooks decided to officially sign with his former team, the Houston Rockets, which tended to reverse Phoenix and Houston's trade in 2011 that had Goran Dragić going to Houston and Brooks going to Phoenix. The last player that became a free agent, Michael Redd, is still unsigned as of February 22, 2013.
On January 18, 2013, head coach Alvin Gentry was fired from head coaching duties. Gentry's firing came right after the Suns' worst opening stint in 28 years. Two days later, the Suns had announced that Lindsey Hunter will take on the role of interim head coach for the Suns throughout the remainder of the season. It was also announced that Sean Rooks would resign from his developmental coaching duties. A day later, Suns fan favorite Dan Majerle announced that he would resign from his assistant head coaching duties as well. Two more days later, defensive assistant head coach Elston Turner announced his resignation from his duties as well. Because of their resignations, Phoenix Mercury head coach Corey Gaines has now gained a more permanent assistant coaching role for at least the rest of the season. In addition, former Suns scout and Shanghai Sharks head coach Dan Panaggio from the Chinese Basketball Association ended up becoming a new assistant head coach.
Because the Suns decided to amnesty Josh Childress' contract, he still gets paid the $6,500,000 that he would have been owed had he played for the Suns this season. While he still gets paid money out of being amnestied from the team for two more seasons, his salary does not actually affect the Suns' actual salary cap. In addition, since Brad Miller's contract guaranteed him around $850,000 this season, he was paid that salary despite being waived by the team and retiring in the process. Also, because Luke Zeller was waived from the team after January 10, 2013 came to fruition, his rookie salary of $473,604 ended up being counted by the Suns' salary cap as well since his contract was guaranteed by that point of the season.
^I: The Minnesota Timberwolves will send their own first round pick (top-13 protected from 2014; top-12 protected from 2015–2016) to Phoenix. If a first round pick isn't conveyed to Phoenix by 2016, then Minnesota shall convey their 2016 & 2017 second round draft picks to Phoenix instead. ^II: The Toronto Raptors will send the least favorable of their own 2014 second round pick (top-36 protected) and the Sacramento Kings' 2014 second round pick (top-55 protected). If both picks fall outside of their protection level, then Toronto's obligation for a second round pick in that year is extinguished and the pick then goes to the New York Knicks instead due to an earlier trade that not only involved the Raptors and the Knicks, but also the Boston Celtics.
^a: P.J. originally signed a contract to play for Spartak St. Petersburg in Russia. However, due to his performance in the Phoenix Suns' Summer League team, P.J. had earned the right to opt out of his contract with Spartak St. Petersburg and sign with the Suns. The last team P.J. officially played for, however, was with the Brose Baskets Bamberg in Germany. P.J. was also using his birth name of Anthony Tucker at that time as well. ^b: Both Diante and Luke had initial rookie scale minimum deals due to being undrafted and spending their first seasons with the NBA. However, their deals weren't officially guaranteed until they continued to stay with the team on January 10, 2013. After the January 10 deadline, while both Garrett and Zeller ended up getting their money guaranteed, Zeller would end up being waived after the Suns traded for Marcus Morris, while Garrett was the only player to have stayed with the team at the end of the season.
^c: Because Josh Childress was amnestied from the Suns, he still gets paid the remainder of his contract with the Suns (3 Years, $21 Million), but his salary away from the team does not affect their overall salary cap. ^d: Childress would get waived by the Brooklyn Nets on December 29, 2012. ^e: Aaron Brooks originally left due to the 2011 NBA lockout in concerns of playing for the 2011–12 NBA season. He signed with the Guangdong Southern Tigers in the Chinese Basketball Association. However, due to the CBA's newest policy during the lockout, he could not return to the Suns once the lockout ended. After his season with Guangdong officially ended, the Suns decided not to re-sign him for a new contract that year. He was initially given a qualifying offer as a restricted free agent with restricted benefits, but he was eventually rescinded of his restricted rights and became an unrestricted free agent. ^f: Brooks originally signed with the Sacramento Kings after the Suns decided to not use his restricted free agent rights that they initially had. Brooks continued to play for the Kings until March 1, 2013, when the Kings decided to waive his contract. Four days later, Brooks decided to return to his original team, the Houston Rockets, for the rest of the season. As a result, the 2011 trade of having Goran Dragić being sent to the Houston Rockets and Aaron Brooks being sent to the Suns more or less ended up being reversed around two years later. ^g: Ronnie Price would be waived by the Portland Trail Blazers on February 21, 2013. ^h: Hakim Warrick was first traded to the New Orleans Hornets along with Robin Lopez. However, later on in the month of November, the Hornets decided to trade Warrick to the Charlotte Bobcats in exchange for Matt Carroll, who would never play a single game for the Hornets. In contrast, Warrick only played one game for the Hornets before the trade happened. However, Warrick would be traded once again before the trade deadline; this time, he was sent to the Orlando Magic in exchange for power forwardJosh McRoberts. Warrick would then be waived from the Orlando Magic two days after the trade deadline; he would never play a single game for the Magic. ^i: Even though Brad Miller announced that after last season he would retire from playing basketball, he still had obligations in his contract that allowed him to come over with the Suns. Once the Suns decided to let him go (alongside Jerome Dyson), Miller would officially announce his retirement from playing basketball. In addition, even though Michael Redd was considered a free agent after his season with the Suns was over with, he never did find a new team for him to sign up with. As a result, Redd would announce his retirement from the NBA on November 6, 2013, well over a year after being an unrestricted free agent. ^j: Luke Zeller first tried out for the Georgia national basketball team during the 2013 EuroBasket Tournament's tryouts at the end of the 2012-13 season before signing with the D-League's Austin Toros (which was also the last team Zeller played for before signing up with the Suns) nearly an entire year after being waived by the Suns on December 27, 2013.
