I don't think you are grasping the concept. You can give 100 WRs the ball in "space" (even behind the line of scrimmage) and they will get run down. If you give TA the same space, he can blaze his way to the end zone leaving defenders falling on their faces. TA has a special set of skills but they require a few steps to get up to speed and make defenders miss. Other ball handlers don't need that as much and wouldn't do much with it anyway.
It's the same reason he is an electric punt returner where most players aren't. He gets the ball in space. If it weren't for all the return killing penalties the last two seasons, he would be considered one of the very best in the game.
Yes, all ball carriers would like to get the ball in space, but no, the results would not be the same IMHO.
