Some say Luke Kuechly is the best linebacker in the league, and his play certainly gives people reason to think so. We could tell when he wasn't on the field last season. Kuechly and veteran Thomas Davis are able to control the entire Panthers defense from the linebacker position. Their impact on the field -- how they diagnose and sniff out plays before they begin -- demonstrates their knowledge of the game. Throw in young hybrid Shaq Thompson, who fits right in with what Carolina does in coverage, and this is a dangerous position group. Thompson can cover tight ends and running backs or he can be sent on certain blitzes. The Panthers could have the best starting unit in the league, but the two teams above have a little more depth.
