Lucas Krull

Correct. From my understanding his character was a red flag during the recruitment process (from his own coach) but his talent was so undeniable they tried to look past it. "im 6'6 and better than everyone else" was basically how my friend described his personality.

The staff thought they could work though it but but decided to part ways before the season because of how unbelievably terrible he treated everyone from coaches to teammates.

Like I said it's been a few years and hopefully he's humbled himself and matured since.
I can see that kind of attitude from a high school kid who was always bigger and better than anyone he played against. But now that he went undrafted, was signed by a team needing anyone to step up at TE, and yet he is barely hanging on to a practice squad job. Yeah, I bet that attitude is MUCH different now.
