No one is worried about our qb situation. We have good depth and competition there this year. Obviously no one knows how well Keller will do yet come game time, but the reports have been encouraging. Matt Hayes just knows what Callahan tells him, and as mentioned elsewhere in this thread, Callahan has been on record for months saying he wouldn't name a starter until the Nevada game week.
The only thing I'm really that worried about is our running back situation since Lucky and Glenn keep getting injuries. We have other running backs, but I think our offense would be more limited with them.
