I'm not sure I directly disagree with any of this. But bottom line for me, its the best rush game designer on this planet, with Felton at FB, a strong run blocking OL and good halfbacks. Few teams can match all that, I would expect it to be one of the best run games around in terms of ypc.
Is it the old 9ers line or the Cowboys line, no sir. But Glenn, Cog, Wood, Miller, Mills...none of them are terrible run blockers, 2 or 3 of them are standouts. Its got to be a top 10 run blocking line, perhaps top 5. And I'm with you on some of Wood's shortcomings just as I was a couple years ago- I wonder if he is part of the reason they ran more zone blocking than many of us expected. Even so, its a good unit designed for the ground attack.
And McCoy, agree with every word you say here, I'll just point out that even when he went to the sideline he mostly did a commendable job of finishing his runs rather than taking himself out of bounds. Thing is, even though you lose the effect of a power back beating a defense into the ground, if you combine him with a good efficient passing game you can create fatigue a different way. What if rather than chilling at the LOS the DL is rushing the passer full-speed all day but we're mostly getting rid of the ball before they get to the QB, rather than holding it for hours? Then you have defenders wearing themselves down pass-rushing, wearing themselves down chasing WRs who with a better passer can now actually hurt them, and wearing themselves down chasing McCoy and his crazy cuts all over the field. And you still have the change of pace, one-cut runners like MG and Karlos who will deliver the knife the second the D sleeps on them. There's more than one way to skin a cat.
Not sure if you've responded by press time but jeffismagic has a good point too.
