Having moved away to Paradise, long before Gillette replaced Schaefer, I have never watched a Patriots Game from the Razor.
But I was the first to criticize Gillette when it was being designed and built, on the grounds that it was too small and obsolescent, even then. Every other stadium in the AFCE is bigger, and the new Jets/Giants Stadium is going to get bigger still.
Plus I said that the Red Seats and general openness, would make it a quietest stadium as compared to the tiny bandbox madhouse, that it replaced. Freezing you rear end on aluminum benches, that were too small to fit, forced everyone to stand at Schaefer. Comfortable roomy seats and no obvious "Dog Pound" area for the passionate fans would hurt Gillette's ambiance and they have.
When the Razor was being built, Box and Red seat income was not shared. That was the reason so many teams wanted new stadiums. But it was inevitable that it would happen, and it did in the last CBA. Now general attendance seating area would be the place that distinguished the "rich" teams from the "poor" ones. Now, the Pats are a "poor" team from general seating revenue standpoint. That is masked by their winning ways, and clothing item sales, but that Will decline when the current run ends.
Is it too soon, (or too late), to talk about how the Razor can be expanded to even get to the average sized NFL stadium?
If the Pats were to try, where would YOU expand it? and HOW? and by HOW MUCH? I can't say having never been to the new place.
