I get the piling on of illini510, but honestly I find both sides of this Ty vs. Tre discussion ridiculous as both sides seem to be picking and choosing arguments based on very small sample size while ignoring seasons worth of data.
For Tre, talent has never been the question. He has that. It's whether he is going to fully commit and show intensity on the defensive side of the ball, and whether he can play an efficient style of offense. He played an absolutely outstanding all-around game against SIUE, but, it is definitely fair to question his defensive effort against EIU (and if you really want the Ole Miss exhibition) and it's also fair to question whether his very efficient start and focusing more on 3pt shots than midrange with a 43% 3pt shooting is actually repeatable for a career 29% 3pt shooter whose historical preference has been midrange jumpers with a pedestrian 1.04ppp.
Meanwhile for Ty, it is ok to say that he has been a much more consistent and plus defender in his career, always gives full effort, and that his offensive rebounding prowess is one of the best in the nation and simply not replaceable. But there also has to be realization that Tre has a much much much larger offensive skill set, can spread the floor, and that Ty's offense is almost exclusively his offensive rebound putbacks and 2nd chance pts. And in an offense looking to spread you out and shoot threes and layups, that really doesn't play towards Ty's strengths.
One hilarious thing though is that one could make a pretty convincing argument that Tre and Ty actually complement each other offensively. Tre historically loves the inefficient midrange jumpers while driving to the hoop and drawing attention and fouls and Ty historically has extreme success crashing the offensive boards on midrange shots. Ty would probably do a lot of cleanup for Tre and if help defense starts accounting for Ty, Tre will get easier 1 on 1 matchups and more efficient attempts closer to the rim.
