I get that, but it is still a very slippery slope. The reality of it is that it would really only benefit a fairly small number of players, and it it became legal to do it, the overflooding of the market is going to drive money that can be made on autographs anyway. That's why Gurley is in trouble now. The dealers are paying them what they are now because it IS illegal, and there are not that many doing it.
I heard some say recently that the solution to the problems above would be that all money generated by autographs should be distributed equally amongst the team, but if you do that, you'll have to do it with all athletes. This will dilute the money down to very little if you have to split it up amongst all of the athletes at a school.
Ultimately, what you will end up is a legal way for boosters to pay the Mark's, Julio's, and Trent's tons of money for autographs while the William Ming's, Anthony Orr's, and Tana Patrick's will not benefit much, if any, more than they do now.
