These situations do sometimes bring up the chance of a "run off" waiver. A coach can't just pull a scholarship without good reason (ie, "he was playing poorly or had a bad attitude, so I kicked him off" is not allowed). So if a kid was pushed out with undue influence and claims he was run off, he may have a case. Which may be exactly why Kirby came out and said Brenton left on his own. The inverse may be why Mehlen thinks there is a case.
Could be an interesting cat and mouse game...and possible lying in the meantime. Let's so hope someone gets caught lying to the NCAA, preferrably both.
