The only truly certain commodities in the SEC are Georgia and Alabama.
But even the two-time defending national champions and the Crimson Tide have some preseason concerns to work through before making another run to the College Football Playoff.
For the Bulldogs, it's a matter of finding a new quarterback and replacing another crop of NFL-bound starters, including one of the projected top picks in this month's draft in defensive lineman Jalen Carter. Alabama is undergoing its own quarterback competition while breaking in two new coordinators.
Across the board, the SEC has at least four and potentially as many as six or seven teams with legitimate playoff hopes.
