The Knight situation is not the same as the LE situation. LE went into alcoholism treatment, and came out supposedly having conquered all his demons, and having become a new person that had everything under control. At least that was the slant of the press that was continually coming out about him and his successes (with links to those articles often posted here on CF). There always seems to be no shortage of folks willing to give good press and glowing character references to LE. We've seen such tweets posted in this thread. And all that could have been true. Maybe LE had a relapse of some kind at CSU.
As a recruit "doing your homework" on LE, how do you process that positive press/exposure? Treatment and counseling for these kinds of problems are all kept hush-hush. I don't think it is nearly as easy to get to the full truth about a coach as you make it out to be.
Also, kids signing up to play for a possibly abusive coach does not justify the coach abusing the players. There are NCAA standards covering behavior of athletes and coaches.

To me, this suggests that it is reasonable for the athletes participating an an NCAA school to expect an environment where they don't have to worry about ducking flying soda cans, and and environment where they will be reprimanded and disciplined in a manner that doesn't involve having a plethora of disrespectful, vulgar, and derogatory adjectives hurled at them.
