A couple of thoughts, Milstein is has not done much with the land that he owns in Niagara Falls in the years that he has owned it, which the Niagara Gazette brings up.

Now if building a stadium and entertainment complex with the land is part of his plan, that sounds great.
Also the completion of International Rail Passenger Station a couple miles north of the rumored stadium would help make it easier to get Canadian Fans there.

All and all I am not too keen about Gillett or Milstein as future owners of the team.
