And just to put things in perspective here is a list of players since I have been following SJU who were better than JR who never played NBA ball:
Interesting list. My take.
Goodwin, Russell, Minlend, Harvey, Thornton and Hill were better than AMJ and better than a lot of other people as well. Add to the better than AMJ list Jason Buchanan, who had a very nice career, Cain, who had not much of a career but a very nice senior year, and Lamont Hamilton, who had a pretty good career despite the fact that eveything about him was soft except his hands.
As to the rest
Name / p pg / reb pg / A-TO
Glover 11.2 / 4.7 / 164-204
Glass 10.9 / 5.8 / 98-206
Middleton 9.7 / 5.3 / 66-120
Brust 8.9 / 4.8 / 236-203
Moses 6.2 / 1.7 / 230 - na
Barrett 5.7 / 2.0 97-122
These numbers seem a pretty fair representation of their respective abilities, except for Barrett, a very nice player who had the misfortune of being coached by BM.
Compare to AMJ
Mason 10.7/ 5.1/ 187-197
By the numbers, AMJ had a career equal to Glover - who played with Hatten - and Glass - who played with Mullin and Berry. Whereas AMJ played with Phil Missere, Gene Lawrence, and Tomas Jasilionustein. He was clearly at least as good as the rest of these players and probably better, and he was especially better than that floor slapping dope Matt Brust, the most overrated player in SJ history.
Conclusion: Mason Jr was a pretty good player with some flaws in his game who had a career equal to Anthony Glover and Willie Glass, also pretty good but flawed players, a fact to which your hatred of all things Norm blinds you.
