Haha true, about the fumble... but hey, he got yardage... he just happened to leave the ball behind.
But yeah, the way I see it... the closer a back is to a linebacker, the more punishment he can inflict and impose on the defense. Like you know in those old football movies when they give it to Kubiak from Parker Lewis, aka Jerry from ER, or whichever "big dude" happens to be on the team? They have a guy on each leg, and two people on their back trying to take the guy down...
Really, you take a 210 pound back who can be tackled by a cornerback, how well are you going to tire out a defense?
Granted, you've got backs out there, like Moe Williams, who never quit on a run, and have wicked leg strength who can push the pile... I just like the idea of giving a Ray Lewis or Julius Peppers the ball, rather than handing the ball off to Ronde Barber's IDENTICAL TWIN BROTHER.
That's why I love Corey Dillon... he's not 260, but he's still a bruiser, and it's guys like him and Jamal Lewis who are breaking the single-game rushing records... not Tiki, not Portis... and you know why? Come 3rd, 4th quarter, that defense is sick and tired of working their ass off to bring the big man down. When you have a quick back, like we were discussing with a QB who can get rid of the ball... you get an elusive, slippery back... and you get him in your sights, you're going to crush him. You take a 260 pound bruiser, and you need to worry about bringing him down, not laying wood. You need to wrap that guy up, where's the fun in that?
