I think we have enough rb's to rotate throughout the game. Heard's a better runner anyway, and Swoops can't throw. Besides with the exception of Burt we don't have any receivers who can catch the ball and in a wishbone you only need one.
You can't recruit lineman to run the bone that are quality. The top Oline kids know that the NFL is a pssing eague and to be able to make it in the league you have GOT to be able to pass block. Run blocking in the NFL is important too but not as important as pass blocking. Not knowing how to pass block gets people killed-- (usually the guy wearing a jersey number as low as 1 and as high as 19) and NFL teams won't draft a kid that blocked 70 times a game on the ground and 5 times a game in the air.
