Wow, I think that is a bit unfair.
I didn't mean it as a dig against Nesbitt. I think Nesbitt is an outstanding player, and don't think we could have asked any more from him this year.
But if you look at our offense statistically, what you find is that we have lots of short runs, lots of long runs, and a higher than average turnover per play ratio.
When the offense works, it's because we got a long run to make the drive short, so we risked turning the ball over less.
When it doesn't work, it's because we didn't get a long run, the drive was forced to have more plays in it, and we kept having to roll the dice on a turnover.
Look at Dwyer's yards. He had 1500 some odd yards this year. Take away his TD runs and he only had like 800. That's an indicator. It's awesome, I like it, but it's an indicator of what our strength is, and if the badguys can take away that strength (long runs) then our weakness (higher chance of turnovers per play) plays a bigger factor.
Nesbitt, due quite possibly to early injury, was not able to be the long run threat that our RBs were. Therefore, if you let Nesbitt keep the ball, it's the highest chance you have to achieve the defensive scheme I mention.
I think our OL will be better next year because we'll have people on the bench who can replace the starters if the starters suck. Period point blank. PJ said it himself in one of his call in shows ...
"some players are not putting forth the effort because they know they can't lose their starting spot."
