I think we put a lot of eggs in the Mo Washington basket, and did not make the right adjustments when he flamed out. The injuries have been tough, because you'd think one out of Mills, Thompkins, Scott, and Morrison would be healthy enough to play. But (especially with how vague they are on injuries) that also seems like a bit of an excuse, and having no viable upper classmen behind Mills is on the staff. Tough to convince transfers to join up with how Mills finished last year and seemed poised to be a workhorse, and plenty of teams have freshman/sophomore backs take big roles. So I really don't know if it's just hindsight saying we needed another back before the year (people were calling for it, so that's a tough sell), or if they just couldn't close the deal on a transfer. Or really believed the guys we had would break out, and injuries got in the way.
I'm optimistic about our depth for this year, since I'd be shocked if that amount of injuries happened again and they have a year of experience. I'm willing to wait based on what they did with Ozigbo and Mills progression, even though he was still way too boom or bust. But I can understand not buying it, and there's a solid argument that real depth has more than 1 upperclassman RB. On the other hand, injuries are pretty random and it's quite possible that guy would've been banged up too. They had 5 guys (including Johnson) they were willing to roll with when healthy, that's some serious bad luck to have injuries to most of them at once.
