Couple of notes...
I think they wanted to get PJ Davis and Nealy on the field at the same time and made the switch to the 4X3 versus the 4X2. This allows Paul to be a rusher to help with pass rush. I wonder why they picked PJ over Demond and Noble. They all three seem very good. Perhaps Paul's run until the end of the play is the difference maker. FYI, I am all in on PJ Davis. I love his passion for the game.
Klock is the only freshman to break the 2 deep for OL. We all know Brown could go if needed this year for OG. Marshall is getting praise, but I think CPJ would like to redshirt him. These might be the three freshman OL most likely to play in 2014.
For some reason I think OReilly may be slight better than Burden, but there is something about Burden the coaches like. It could be attitude or the number of snaps he can take or his command of the offense line. Either way, the coaches seem to be leaning Burden.
Lynn and Waller should make the two deep after the first two games.
Demond Smith is an "or" for both safeties starting spots. He could win a starting spot or ay least be the first off the bench.
Freeman at DE is the only starting freshman at this point.
Marrieweather at DE and the Austin twins at CB are the only freshman to crack two deep on the defense.
