Some of the things @dsddcane says are true, some are plain fiction, but most or massively over dramatized and skewed by his bias toward being a loud-mouthed drama queen.
He's got a big mouth and is constantly airing dirty laundry that he shouldn't be airing. There's no doubt in my mind that he helps sow the seeds of discord in the lockerroom and/or stokes the flames.
I actually like Hightower, but if him leaving means it'll keep the cancerous drama queen @dsddcane away from the program, that's a sacrifice I'm willing to make.
