The 2009–10 Mid-American Conference men's basketball season is the 64th college basketball season in the conference's existence. The conference features 12 teams in two divisions, East and West, who will compete for the Mid-American Conference (MAC) regular season and tournament titles.
None of the twelve teams made head coaching changes from last season, although some gave their coaches contract extensions. Ball State gave head coach Billy Taylor a two-year contract extension after the Cardinals shared the MAC West Division title with Central Michigan. Taylor finished second in the Coach of the Year ballot sponsored by the Conference and has held a 20–41 record since taking over the program. The contract extension will keep him at Ball State through March 31, 2014. Other changes with the Ball State program include Bob Simmons being promoted to associate head coach and Mitch Gilfillan hired as the Director of Basketball Operations.
On the east side, Bowling Green gave their head coach Louis Orr a two-year extension that will also keep him through the 2013–14 basketball season. He beat out Taylor for the MAC Coach of the Year ballot last season. In Orr's two seasons at Bowling Green he increased the team's conference winning percentage, going from 3–13 in the year prior to his arrival, to 7–9 and 11–5 in his two seasons at the institution. To completement the contract extension, Bowling Green announced that Dennis Hopson would join the Falcons as an assistant coach.
The Akron Zips gave their head coach Keith Dambrot a lengthy contract extension, keeping him through the 2015–16 season. Dambrot had led the Zips to four consecutive 20-win seasons in his five years at Akron (his first season only had 19 wins). Those five years were capped off with an NCAA Men's Division I Basketball Championship Tournament appearance in the 2008–09 season. However, the University lost a key assistant coach when it was announced that Jeff Boals would leave to become an assistant at Ohio State. Boals was a key figure in recruiting Zeke Marshall, a 7-foot center who has been Akron's highest recruit in recent history. To replace Boals, Akron hired Dan Peters, former Ohio State assistant coach who helped lead the team to the 2007 National Championship Game. Peters role with the Zips will be the Director of Basketball Operations.
On October 28, the members of the MAC News Media Panel voted in the Preseason Media Poll. They voted Akron as the favorite in the MAC East Division and Central Michigan in the MAC West Division. The Zips come off of a 2008 where they represented the Conference in the 2009 NCAA Men's Division I Basketball Tournament, and Central Michigan won a share of the MAC West Division title last season.
The media also took a vote on who they think would win the MAC Tournament at the end of the season. Unlike the preseason votes, the media would only select the winner of the tournament, and not the placement of the teams afterwards. Akron received the most votes with 19, followed by Buffalo with two votes. Northern Illinois, Kent State, and Bowling Green each received one vote to win the tournament.
Five Mid-American Conference teams opened up their season on November 13, the first Friday after the 2009–10 NCAA Division I men's basketball season began. Miami first played the Tigers of Towson University in their home court in Maryland. While the RedHawks were able to build to a 42–37 lead at halftime, Towson would go on a 10–2 run in the second half and eventually sealing the victory with a final score of 82–71.Northern Illinois would also begin their season with a loss, losing 55–77 against intrastate opponent NorthwesternOhio began their season with a win Ohio Valley University by a score of 101–72 in the Convocation Center. Five Ohio players reached double-digits in scoring, led by Ivo Baltic who had 20 points in that game.Ball State was also able to begin the season with a victory, theirs over Horizon League opponent Valparaiso. Six players from Ball State were able to score over ten points, which is the first time in over ten years that it has been accomplished by a team. The Cardinals won by a score of 88–78. Finally, Kent State began their season by hosting a version of the 2009 Hispanic College Fund Classic. Their first match-up in that tournament was against the Samford Bulldogs. The Golden Flashes snuck out a win in that game, 69–66, to keep their home opener streak at 13 games.
For the eighth year, ESPN organized an event that's known as the BracketBusters, which features teams from Mid-Major Conferences which face each other in order to improve their strength of schedule. The matchups will be announced on February 1 with the teams facing each other on February 19 or 20, 2010. The MAC is tied with the most teams in the event, with them and the Colonial Athletic Association having 12 teams each featured in the field.
Ball State, Bowling Green, Central Michigan, Kent State, Miami, and Ohio will all host games in their venues, while Akron, Buffalo, Eastern Michigan, Northern Illinois, Toledo, and Western Michigan travelling to opponents' arenas.
As a part of the Preseason Media Poll, the members also voted on the Preseason All-MAC East and West Division teams. Akron and Eastern Michigan had two players in the East and West Division polls, respectively.
