I think the answer to that is, "he doesn't think of himself as a mid-level player." I think any player worthy of playing time needs to think of himself as, at very least, having a very high ceiling. So I don't begrudge him that. Also, while Butler sucked last year and I can't be arsed to look into how good or not they stand to be next year, the Big East tends to be bunched up, and so going from 6-14 in conference to, say, 11-9 and on the bubble is probably not out of the question. Finally, while we have misgivings about Ali (especially now that he's gone), statheads and analytic nerds tend to love his game. Maybe there's something to that, and maybe the "actually, he's not that good" camp is right, but again, you can't blame him for believing in himself.
For better or worse, this is the transfer portal reality now, and this is gonna happen from time to time (and hopefully not more frequently than that) with our good players. I for one am not gonna try to take such transfers personally as a Zip fan (although I would be f***ing heartbroken if Enrique left, I would try not to be ANGRY).
I hope that Groce and his staff respond to the advent and popularity of the transfer portal by scouting low-major transfer portal diamonds-in-the-rough thoroughly, and well. If any of our players feel like Butler is a step up, well then, maybe we are a step up from Nebraska-Omaha, or whoever. Or even D2 (Max Strus went from D2 Lewis (Ill.) to DePaul to the Miami Heat).
