I like Yogi better than Mason don't get me wrong, I think he would win the battle for the backup spot.. Just similar in stature and game.
Prob w/Mason is he turns down open looks on the perimeter and when he drives his wreckless abandon is disheartening (to me).
Mason has all the tools, quick first step, athleticism, good 3pt shot, etc, but Yogi plays the game right. Maybe he can teach some of these things to Mason.
I can visualize Yogi's pick and pop w/ Giles or Bjelly. It would add so much to our offense, clear driving lanes, open up other shots for buddy or bogi.
Yogi is good and imho (at this point) a serious upgrade at backup pg. Plus hes basically the same age as Mason.
So many positives
