A few interesting moves on Defense:
Meier might have beaten out Hardy at DE, which has to be considered positive if true, because Hardy was playing last year.
Mabin appears to have beaten out both Fleming and Draper, which is also good, because those two played last year.
We appear to have a Top 5 at LB--Alston, Spearman, Perry, Jewel, and Bower, but only Alston's spot is secure. It looks like the competition for the other two spots will continue into the season.
Cooper isn't listed at DT. I think it is because he is hurt. He's been pretty productive, so if the under classmen have beaten him out that is pretty surprising.
