I am a huge fan of James McCluskey's NFL upside...and this has nothing to do with his agent being a friend of mine. Think of all the rave reviews we've heard about Mike McLaughlin from Baltimore and Denver. How versatile he is...how the NFL needs more blocking fullbacks, etc. Now imagine a player who fits many of the same needs but can also catch the ball.
The flipside is that for all the hustle and hype people have for pluggers, scrappy fullback types, they are also a dime a dozen. McLaughlin is on his second team without ever having played a snap in a live game. I see McCluskey in that same mode, but I think his offensive skills will keep him on a team as a free agent.
If anything McCluskey was underutilized due to injuries and offense during the later part of his BC career. In 2008 -- before he broke his leg -- he was a solid runner and pass catcher. As his career progressed and the offense changed, he didn't touch the ball as much. But that didn't stop his blocking. McCluskey opened holes the past two years and won most of his one-on-one battles.
As for measurables, McCluskey has the size. He's probably a little slow at 4.92 for what any NFL team would want, but as a FB/special teams player, he can get away with that.
I am 99% sure that McCluskey will not hear his name called this weekend. Conversely, I think he will be a popular guy once the lockout really ends. If he finds the right offense and the right depth chart, he can make an impact in 2011.
