Per CBS Sports' Pete Prisco, Luke Kuechly is #2:
2. Luke Kuechly, ILB, Carolina Panthers -- He led the NFL in tackles as a rookie. That's impressive. He was all over the field and did so without the help of good down tackles in front of him.
Not bad but I think he should be #1 but that's not being a homer or anything. Glad he is getting the recognition he deserves.
