trained a fighter who was in the famed national championship tournament that tamerlan tsarnaev was in in salt lake city in 2009. he observed tamerlan for a week at that tournament. here is eddie bishop. >> flashy guy. he has cowboy boots on leather pants flashy shirt, hat, he was -- he was eccentric. he was a talented fighter. he could punch. he could definitely punch. i notice he was lacking a key element, you know. he lacked heart. you can look at somebody in a ring and say that guy can punch, that guy can move just know the little subtle things, you know, he lacked heart as a fighter. >> so he got to the national championships. didn't win them just lost the bout and some coaches are putting together the reasons why, didn't put it together at the end. the next year he gets disqualified because he's not a u.s. citizen. he thinks that turned him down that dark path.
