The first two rounds they have us taking Bandon Spikes ILB, FLorida and Trevard Lindley CB, Kentucky. This would be the kind of move you would make if you were switching to a 3-4. Spikes would be a good compliment to Meco in the middle and Cush and Barwin would be your OLBs. Mario would shift to LE. Of course with a 3-4 you would need to have a big NT (like a Casey Hampton) and may need to slide Smith to RE or find a journeyman RE to compliment.
Lindley is a bump and run man to man corner. He would be horrible in Zone. So, he could be a DR replacement.
