Favorite: Bullis (8-2)

Traditional IAC powerhouse Bullis has reloaded and looks well-equipped to reclaim the IAC championship after falling to Landon last season.

Contender: Landon (7-3)

Around the league: Landon surprised Bullis by taking home the league title in 2012, but will have a tough time repeating against a traditionally loaded Bullis roster that features Rutgers-bound lineman Justin Herron and Western Michigan commit Devonte Williams. . . . Landon will benefit from a full season of senior Kyle Hartman at QB. Hartman came on for the Bears’ last four games last season, engineering three conference wins — including the title clincher over Bullis. . . . St. Stephen’s and St. Agnes (6-4) may just challenge for the IAC title after making a jump from 1-8 in 2011 to relevance in 2012. QB Ish Seisay is a threat with his arm and his legs, and has some explosive targets in two-time all-state WR Sam Gallahan and a likely future star tight end Andrew Trainer, a 6-foot-6 sophomore.
