Not my area if expertise either but It would almost shock me if 2/3s goes to the player per jersey. That seems like a high number given all the different parties involved probably dividing that pie.
Agreed. No insider knowledge here but I'm guessing the 2/3 vs 1/3 cuts are from the royalty, which is probably in the 10-15% range. So if Brock's jersey sells for $120, the total royalty might be $12-18, and Brock might get $8-12 of that.
