Meh, not sure how big a difference it makes. The line got really banged up last year, but how much did it really hurt us? What's the difference between Cordaro Howard, Mansfield Wrotto, and Cornell Green? After all 3 of those guys got hurt last year, we turned to Erik Pears, who is now an entrenched starter. Same with Urbik at RG and Wood at C - those players only started there due to injury last year, and are now unquestioned starters at those spots.
I'm sure if Young gets into a game anytime soon, there'll be a dropoff from whomever he replaces. At least until Young learns the playbook. But fundamentally, I don't see our crappy backups as being that much worse than our crappy starters. We'll see, I guess.
