Despite all this talk of the NFL coming to town, I doubt it will happen. First, the barriers to entry are too great. The cost of buying an NFL has been estimated at a cost of $1B, add to that the cost of building a new stadium or significantly redeveloping Rogers Centre. The cost would be at least $2B and if anyone thinks that any level of government will provide any form of funding is nuts. I don't see any private investor willing to pony up $2B on bringing an NFL team to Toronto.
Second, there is the CFL and the Argonauts. Would the NFL be willing to risk harming the 2nd largest and most established professional gridiron league in the world that in some ways acts as a pseudo development league? The fact that the CFL exists also reinforces the NFL's position in the eyes of US antitrust regulators. Competition for players = competition in the market = not a monopoly. Having the CFL around benefits the NFL. The CFL has a long history and tradition in Toronto, NFL would likely hurt the Argonauts and Tiger-Cats and could potentially lead to the CFL's demise. Don't expect the Argonauts, CFL, and some in the government to roll over for the NFL, see proposal for Canadian Football Act 1974 (
http://en.wikipedia.org/wiki/Canadian_Football_Act) though the concept/context is somewhat dated. Like it or not, there is value in protecting a Canadian cultural tradition/institution for both Canadians and the NFL. Canadian football and the Argos deserve better.
Finally, although many claim there is enough interest in the NFL game in Toronto to bring a team there, there simply isn't. The NFL as a league is built on hype, though the Bills Series may provide a poor indication of how successful a 'local' team may be, the fact is that poor attendance and limited fan excitement will do nothing to help the appeal of bringing a team to Toronto. The NFL isn't looking for the type of quiet corporate environment Toronto will bring, let alone less than packed houses, and expensive tickets. They want to be able to market the hype: crazy screaming fans, sold out stadiums, tailgate parties, etc. Judging by the Bills Series and Leaf games, that's something Toronto can't and won't bring to the NFL. Toronto is supposedly hockey crazy and support for the Leafs is the highest out of all the teams in the NHL. If the Leafs can't muster up fanatical fan support in Toronto, what makes anyone think that the NFL can? The NFL wants nothing more than to be the biggest player in town, in Toronto, it would have to settle for being #2 behind hockey.
