I seem to recall Clemson struggling with depth issues just this year.. And Ala had one of their down years when they only had 6-7 dline to compete with.. Every team has depth issues, Its just a matter of if thats the yr the injuries hit that spot.
Look at TCU, no one has taken more hits than that QB and they made it thru the season, Im sure they might not be 11-0 if he went down, Kansas look what happened with the QB got hurt.. It happens all over but too many here dont watch other teams to see it.
We had enough depth to take every game into the 4th but 1 and if the oline had played better we might have survived it even better to a 8-9-10 win season.
