I don't think there is any question that Orgeron recruited very well on the DL. I don't think its any secret that Nutt, as far as production goes, hasn't recruited as well as Orgeron did. We'll see how good guys like Thompson, Martin, and Bennett are eventually, but I think it will be tough to pass the productivity of the Orgeron DL recruits.
However, as far as I can tell, he certainly has surpassed Orgeron in recruiting as far as LBs and DBs. In the secondary we have 2 freshmen corners getting PT, one former Nutt walk-on (from Hargrave) starting, and Ingram (Orgeron) and Jackson (Nutt) sharing FS responsibilities. Johnny Brown (Orgeron) and a player initially recruited for RB that Nutt moved to CB (McGee) are the other two players. Oh, and the backups are all Nutt recruits. The LBs have Kight (Nutt) starting with two seniors (Walker, Cornell), one of whom is sharing PT with Shackelford (Nutt). All of the backups are young Nutt players (2 true frosh and a junior).
But you are right, losing guys like Powe, Lockett, Laurent, and Scott are going to hurt next year. The experience factor will be switching from the back 4 to the front 4 next year.
