(I think my math is right.)
A lot has changed in the last five weeks - I don't even remember putting Carson Wentz on my board and now he's heavily projected to go 2nd overall - so this should be an interesting change of pace from my last draft. Updates will be weekly or bi-weekly from here on out.
Summary: I really don't think McClain is a 4-3 inside linebacker. The speed and lateral range just isn't there for me, and I think he would be exposed because he will overpursue gaps. McClain is great for 3-4 teams because he can play inside, but also move over to the outside if needed temporarily. His best fits are at 3-4 inside linebacker and 4-3 strongside linebacker. McClain is a solid prospect who will likely come off the board in the top 20 picks.
Player Comparison: Bart Scott. Scott has great instincts and size, and is a leader at inside linebacker in the 3-4 defense.
