Polian is gone. Get over it. The Bills had 4 shots to win the SB under him and failed, mostly because they didn't face pretenders like the Bears in the SB's. And given his irascible nature, he wouldn't have survivied after the Bills missed the playoffs in 1995, at best. As for Butler, he died, so I don't know what you're getting at there.
Because I've found that those who claim they "would" spend more, actually don't spend anything at all currently. IOW, it's all talk. So, how many games do you see a year? I'm guessing by your evasiveness, none.
