The talent might be better but not the experience in general and especially in the system.
If I had to guess, I'd say the number one biggest problem right now is a bunch of young players who don't understand an overly complicated defense.
Just a theory of mine, but I believe that is why guys like Pitt Brown, Armani Reeves and Cam Williams are seeing the field while Vonn Bell, Cam Burrows and Trey Johnson (not to mention all the redshirts) have not.
Experience is trumping pure talent but unfortunately the experienced players aren't up to Ohio State's standards right now.
That is absolutely the coaches fault and I blame them for not simplifying things in an effort to let the youngsters make a bigger impact. In addition to finding a leader and football player, they reportedly simplified things substantially for Boren last season which I believe made a substantial difference in the Ds overall performance.
If the system continues to be too complicated for even the best talent to excel in because they're thinking too much (hello Sabino and Curtis Grant) then that is a major problem.
However, given the overall attrition on the team (look at the 2009 and 2010 classes- they're almost at the 2003 level of non-contributors and they would be the guys who should know and help teach the system right now) combined with injuries this season, I am willing to give the defensive coaches another season.
I do expect to see significant improvement next year or I will be first in line demanding changes be made.
Edit: oh yeah, and the "experienced" players like Williams and Reeves have only had a few years to learn the system so I use that term loosely and relatively speaking. Once again, go back and look at the attrition from the '09 and '10 classes- or just go back and look at my post a few comments back.
