From a players perspective I think they would be disgusted by it and outraged.
However from a business standpoint the NFL cant get any bigger in North American and its time to get viewers overseas.
In the end the players work for the league... If your boss tells you the company needs you in the UK what argument do you have? It will result in higher salaries and we know from Soccer the Europe isnt afraid to spend money so.....
I think its a great idea and cant wait to have an american football game in the morning instead of watching 90 minutes of a bunch of diving bitches who act like every goal is the greatest one in there career.
Go UK American Football Go
