There is a chance Woods may have better stats even, but Kupp is the better player, more valuable better, the transcendent player.
Transcendent is something that is unique to the sport that changes what is typically thought of.
Magic Johnson, Larry Bird, Mike Martz, Greatest Show on Turf, Curry and the Warriors, etc. It is almost like Kupp has this ability to disappear and the defense doesn't know where he is and all of a sudden he is standing catching a pass either in space or even in tight coverage. He takes hits can run after the catch, can get open short, deep, intermediate, etc. and nobody can figure out how he does it.
I have never really ever seen anything like it.
