When asked on television "Can a guy who's five-foot-nine, 175 pounds make it in the pros?", he answered "Yes, he can. But it's a matter of ability and not size. I feel I can play; I don't know for sure, and those questions will be answered in the future."
If the Patriots had kept him, and made him the starter, they would have been at least competitive. When Parcells showed up? Fryar may have stayed here. We can only imagine.
No way someone with these accomplishments would not have succeeded in the NFL:
His career CFL statistics include 41,355 passing yards and 270 touchdowns. He holds the professional football record of 6,619 yards passing in a single season. He led the league in passing five times in only eight seasons. He once held four of the CFL's top five highest single-season completion marks, including a record 466 in 1991 which was surpassed by Ricky Ray in 2005. His 48 touchdown passes in 1994 remains a CFL record. He earned three Grey Cup MVP awards, and was named the CFL's Most Outstanding Player a record six times (1991–1994, and 1996–1997). He passed 5,000+ yards six times in his career and remains the only player in pro football history to pass 6,000+ yards in a season twice in his career.
When they let him play, they won. It literally took benching him ('88 & '99) to stop him.
