McClain is just inconsistent. One week, he will be okay and the other week, he will look like the best LB in the game. If I am remembering the game correctly, I remember seeing one of the more dominant performances by a MLB ever against the Dolphins from McClain. I credit him more for that win than Romo and I credit Sean Lee for the win week 2 so we won two games because of our linebackers.
The inconsistency links back to his work ethic. If Rolando McClain had a Sean Lee work ethic, I feel he would be one of, if not the best, LB to ever wear the star. Hitchens will be a solid, okay player, possibly more steady than McClain but will never have those dominant performances that McClain has every now and then.
