There is no reason to fight the NFL. People often forget its a two way street. Yes, the CFL loses top talent to the NFL usually 3-5 guys every year, but a lot of NFL teams now are clearly pointing their fingers north when a fringe player gets released who may not have another kick at the can in the NFL. Just in the last 3-5 years I have noticed bigger names making the jump from NFL to CFL and I believe that's a direct result of the best of the best from the CFL heading down south spreading the image of the league in a positive light.
It is in the CFL's best interest to partner with the NFL rather than make an enemy out of them because as we have all noted the CFL is not on the NFL's level.
Like D&P said, I am sure Popp has some strict guidelines for any NFL scout who wants to check camp out and it does make the team seem unselfish when it comes to the aspiration of many of their players to play in the NFL.
