I think Carpenter is a great player and more NFL ready. I think his best position is ILB and he'd be a great ILB in our 3-4.
However, we just signed Ayodele to play that position and I don't think Carpenter would be a great OLB. Lawson is a freakish athlete, freakish. I think Lawson could make a bigtime playmaking OLB. Lawson has more potential to be a fearsome passrusher and he definitely has the speed to run down Westbrook and Moss on all those stinkin screen passes.
I was leaning towards Carpenter until we signed Ayodele, now I'm think Lawson. He could be a star and playing OLB, he'll have the freedom to use his instincts and athleticism.
