The San Francisco 49ers quarterback situation -- the oft-crappy Alex Smith starting, David Carr playing the role of backup and Nate Davis as the lazy third-stringer with potential -- was tenuous at best heading into the season.
Things changed quickly in the last few hours, though, as the Niners announced they have released Davis, their 2009 fifth-rounder out of Ball State, in order to make room for ex-Raven Troy Smith, who was recently released by the Ravens.
Davis was considered a pretty nice QB prospect (at one point, he was the third quarterback on a lot of draft boards, behind Jimmy Clausen and Sam Bradford), but his work ethic's been seriously questioned by Mike Singletary and it seems that eventually the team felt they couldn't risk the possibility of actually having to play Davis if things went downhill for Smith or injury struck.
Smith, on the other hand, has actual experience as an NFL quarterback, and, even more importantly, isn't David Carr.
