an interesting note, Don, is that a lot of the "success" stories about guys going from the AFL to the NFL deal directly with the New York Dragons (which used to be the Iowa Barnstormers). they have a tremendous track record of two things:
1st, whoever their talent scout is, the guy is awesome. in addition to having some of the best players in the AFL, they've put as many guys in the NFL as anyone. QB Kurt Warner, DS (corner) Kevin Kaesviharn, WR Mike Furrey, K Rob Bironas to name a few.
2nd, they play a bunch of white guys all over the field. all four of the guys i mentioned were white. and currently they have a white WR/LB Chris Anthony, WR/DB Todd Doxson, and DS Chris Angel. they are one of the most white friendly teams in all of football, in terms of breaking down caste system positional bias.
