Because Electronic Arts was forced to pay players for using their jersey numbers and other info that clearly matched the real players. SU starts selling multiple jerseys with just the numbers of current players like Shrader, Rhino, Jesse Edwards, etc. We know exactly which players those numbers represent. Could be another lawsuit if players don't get paid.
Anyway, my point was that because of the transfer portal, I would be hesitant to buy a jersey of a current player with his name on it, unless they already made significant contributions to the program. If it just had the number, I would be more likely to buy it.
