(The NFL has) a bit of an issue with their collective bargaining agreement, which has not lent itself to the same, let's say, progressive anti-doping program that the Major League Baseball people have, and similarly at the NHL, i think there needs to be an attitudinal shift from the players. They should be making sure that they're delivering clean sport. They should be making sure that they're not protecting the bad guys, the one or two who may try to cheat or actually cheat.
