Let's be real: There were plenty of red flags that said "this guy is crazy, stay away from him".
There have been for years. Heck, two teams were willing to part ways with him even if it didn't exactly happen under the best of circumstances for them.
That's gotta tell you something.
Missing the point again, unsurprisingly...
The league says "we won't put him on the exempt list as long as nobody signs him."
In other words, don't even think about it.
And as long as nobody does, no worries.
