Honestly I think you'll have to wait until TC to be excited - or not. In the meantime you, me and every Packers fan can hope he'll get better as he gets more experience at the ILB spot and gets farther away from his ACL injury (as you say in your post above).
I have also been among those complaining about the ILB position and was hoping Thompson would step out of his MO (as he has done on occasion) and address it in UFA. For those who thought Kendricks was the answer, would you have wanted Thompson to reach for him at #30 IF the Packers rated Randall in a talent tier above Kendricks, Anthony and the other ILBs? By pick 45, Anthony, McKinney, and Kendricks were gone (Perryman at #48). Is anyone advocating Thompson should have gutted this draft and traded up to get one? For example, by my math it would have taken picks #62, #94, and #129 (451 pts on the trade value chart) to move up to pick #44 (460 pts). If the Packers rated Dawson about the same as Ryan, should Thompson have picked Dawson at pick #94 anyway (Dawson was picked at #99)? I think it's clear the Packers didn't have the ILBs rated as highly as some here did. And I think it's likely they had Ryan rated higher than most fans and perhaps other teams. BTW, that's another reason to feel good about the pick if you need one before we see what he can do in TC: (If you believe him) Thompson and his staff had him rated higher than where he was taken.
