Yup.
Kelce and Fred are very different players. Kelce moves better and is better in pass pro. Fred is much stronger and better in the run game. I think where Fred gets the nod is, no center in the league can stone 350-pound nose tackles by himself like Fred can, and no center in the league reads the defense like Fred. Really, when talking about making offensive calls (not just line calls) and blocking on the interior, it's not close.
Mathis may have been better than Martin at one point in their respective careers, but not now.
Herremans, really? He was the weak link of the Philly OL last year and, IMO, far and away the least capable of the 10 OL in the discussion.
I really love the fact that our guys are the hardest working position group on the team and don't really seem to care about the hyperbole. They set the tone for the team, in every way, and IMHO, that's nothing but good.
