To me, the biggest problem with the Frost era has still been in getting the roster turned over and getting the right players in place. Too many holes in too many positions. Having almost the entire defense back next year is huge IMO, though we still need a pass rusher.
The offensive side of the roster has been the bigger problem. I don't blame Frost for the O-line's regression in his second year - much of that was just a product of losing the last of Bo's guys. But I think Frost does deserve at least some blame for the collapse of the WR and RB squads. I don't blame him for Riley's guys leaving, but there's been way too many of Frost's own recruits leaving in those groups. What I don't really know is whether it's something Frost or the other coaches screwed up or if it's just rotten luck. I mean, obviously the reasons Wan'dale isn't on the team anymore are completely different than for Washington. I'm cautiously optimistic about the WRs, although depth could get scary in a hurry. The RBs, I don't even know what to think. I know we had some injuries and illness last year, but I still feel like having to play Wan'dale as the #2 RB is a big red flag - was there really no one else who could play, at a position that's usually fairly easy for new guys to adjust to? And though we've got a lot of guys who look promising for this year, we've also got a lot of guys with a history of injury issues.
