Agreed with top 8 but would put Kuechly (especially if he can play OLB and ILB in a 4-3), Coples (because of potential), Reiff (play multiple positions on the line), and Glenn (same as Reiff) in a class above the others you have listed. Decastro is great but can't play T like Glenn and Reiff can. Lastly I'd be ok with Poe as well because it would suck to miss out on the Ngata again (Kelsay, Williams, Poe, Dareus is a big beast line)
