Do RB's effect Def.
 

Does a RB have any effect on the opposing defense.

If you have a 6'1 260lb RB crashing into the defense 30 times a game, does it effect the defense in any way, as compared to having a 5'11 190 RB.

I know players have endurance ratings, so, I'm wondering if maybe a Bettis / Okoye RB has the "wear" down effect.

I dont know if this has been tested or discussed in the past.

Thanks for any replies

I've never seen anything on this, but I would tend to guess "no." If so I think it would have come up somewhere. Plus, Jim just came out saying that height/weight don't really matter all that much, so this is just that much more unlikely.

Would be cool, tho...
