I do see the possibility of another 2010, but really doubt it.
DB's Lester will have Barron's spot as leader, but will have Sunseri and Ha-Ha out there with him (Vinnie got lots of snaps in 2012) +
LB's Nico will be in Don'ta's spot as leader, but will have CJ who played tons in the last 2 years and Trey who got some quality snaps +
DL - in 2010 all of the guys were 1st time starters pretty much, tho they had played lots, this year, Square and Williams both are returning starters +
OL - what can anyone say, as long as they stay healthy...maybe the best in the country ++
Wr's - all new starters, but the probables all played a good deal this year (and IMHO, there will be more speed and Height) shaky +
rb's - lost MFBATR. but with CBEL and Jalston..whoa... and then there is Dee and Blake and if needed TJ... have to say wow +
TE/HB - have 1 starter out of the 3 used in 2012, this is a real need, rate as - (H Jones and Volger got very few snaps last year)
QB - teams should be wary of AJ's play action passing after seeing the BCSNCG, but with the running game and fast tall wr's, he should be better this year (do I sound like I am describing GMac's 2nd year?)
With the playa's that Arky lost all round, I see them as worthy but not quite good enough, and with LSWho- Who really knows? on paper they look great, but may depend on how the grass in Les' teeth goes?
