There was no speculation in what I posted, it was a complete recounting of what happened. Battle was preseason all B1G, he was on the preseason watchlist for national best small forward.
Do you think Battle actually got less skilled from last year to this year? That his offseason practice actually made him worse? Whose job is it to get the team to jell, its the coaches' job. Did Battle jell with the team in year 1, he most certainly did, so it's not that Battle is a person who can't get along. Battle played worse because of the roster construction and playing him out of position, those are all coaches' decisions.
I guarantee Battle will go to a different program and have much more success because the coach will know how to put his players in a position to succeed, so the variable will not be Battle. He knows it as well, that's why his position is anywhere but here.
You are the one creating conjecture ("Maybe the other guys on the team didn't like him.") and making up reasons to support your desired outcome, I guess you will accept any reason accept coaching.
