"I think I've had good practices since I've been here. Yes, I think about it (contract problems) occasionally. I don't think there is any better receiver in the league. But I don't like to pick a receiver's name and salary and compare myself to them."

Brown, 24, said the Philadelphia Stars and the new Jacksonville Bulls of the U.S. Footballhave expressed interest in him. "If things don't go well here . . .
