I met him a couple times too and he seemed like an ok guy to me (He hung out at Ken's a lot). On the other hand, I heard from numerous other people that the guy was a complete jackass. He loves to fight. A few years ago, Sebastian broke some guys jaw in a fight. According to my brother (Tallahassee Police Officer at the time), FSU booster bought off the kid's parents that he beat up to keep them from pressing charges. That was the year we won the National Championship in 2000 so I guess it was money well spent.
The guy obviously has a drinking problem. If he's not careful, he's going to find himself back in Poland.
