Yeah, one might understand McGusty feeling that way, he was a higher ranked recruit. But it was also Shepherd (who knows why), CJ, Lattin, and Odomes. They felt "owed" from the 2016 run, like they paid their dues and Trae was stealing the show.
And that core of whiners, backbiting, and jealousy with Trae was also a big reason we went 11-20 the previous year.
If anything, Trae rescued that team from another 11-20 season. Anyone blaming that on Trae wasn't paying attention to what he added to an average group.
