I am trying to answer a friends trivia question, can anyone help me?
Name an nfl player who previously played for the Cowboys, but is currently playing for another team, who is white, and played between 1987 and now. He may currently play for (and/or reside in) either Miami or Houston. He is not a lineman, but has a leaner more athletic build..those are all the hints that I have, anyone got an answer? I'm coming up w Vinnie Testeverde...but aparently thts not it.
