Dude, you're flailing, let it go. We all get things wrong. Shady is an elite back and borderline HOFer. Beyond stats, my eyes tell me this. He's just a rare, rare talent that I think can age well because he doesn't seem to take many big hits and doesn't just pound into the line.
I'm sure you also realize it's much easier to rip off some runs when you're the change of pace guy coming in against a tired D. How did Karlos and Mike fair in the games shady missed?
You're choosing an odd topic to make a stand on.
