exception: from 1966–1969 when the NFL/AFL championships were basically NFC/AFC championships, but the leagues were still separate
High school state championships
Monthly/weekly awards, e.g. NFC offensive rookie of the month, FedEx Ground player of the week
Minor team awards, e.g. Rams rookie of the year, Jets teammate of the year
NFC/AFC All-conference selections
Franchise records, e.g. "Jacksonville Jaguars all-time leader in wins (3)"
"Jersey no longer issued" There could be several reasons a player's jersey has not been worn since his retirement
Arbitrary milestones, especially if the player was not the first to achieve it, e.g. "third player to rush for 800 yards and 13 touchdowns in a season taking place during a leap year"
Arbitrary records, e.g. "most seasons with 1,200+ receiving yards and 12+ touchdowns in NFL history"
A section link to a highlights and awards section of the article, e.g. other awards and honors in Drew Brees' infobox. The table of contents already serves this purpose.
"Champion" (as in Super Bowl champion) is not a proper noun, so should not be capitalized. "Championship" is typically capitalized if it is part of the name of the game, e.g. BCS National Championship.
Hall of fame inductions do not need to be stated in the "highlights" section if they're already displayed with banners, e.g. Pro Football Hall of Fame.
Wire services should not be italicized. Typically only magazines and newspapers are.
Awards and highlights should be in descending chronological order, with the most recent listed first. The exception is post-playing honors (e.g. retired jersey, halls of fame, etc.), which should be listed last.
When listing All-American and All-Pro selections, there is no need to list the selector. If one selector has a player on its first team, and another has that player on its second team, the player is a first-team selection. List it as "First-team All-XXXX (19XX)". Note: first-team All-Pro selections listed at the top of player bios on Pro-Football-Reference can be misleading. The site only lists AP selections, as explained here, and disregards all other selections. Scroll to the bottom of a player's bio to see all selections.
