My Only concern with Cardale as starting QB is if he can stay healthy all year long. I re-watched the game last night and if the rest of the schedule dives at his knees like VT did to tackle him....could be ugly. Everyone knows that you can't, or Most won't be able to take 12 down with a normal up high tackle. Cardale isn't as nimble as JT, and wasn't able to side step or juke the defense on most of those tackles. I think his best move is the Steamroller or Hurdle. :)
I'm not at all worried about the depth, just for Cardale's future.
Hopefully tOSU get's through the season OK, and last year's injury totals will give some good karma on 2015.
