Speaking of economics, should we consider this?
The Red Sox currently outright own Fenway park. A new park would undoubtedly add expense to the running of the team via capital improvement financing. I'm curious to know how the "new park" crowd feels about the potential for the on field product to suffer due to budget constraints vs. maintaining the current budget and competitiveness with Fenway as the lower cost option.
Personally, I think the arguments for a new park are compelling. The average size of a person is much larger in 2012 than it was in 1912. Those seats are not comfortable for people even a little bit above the current average size of a person. I've always thought the reasonable compromise between making things more accomodating for contemporary fans and tradition is to add more super structure and expand the seating area while upgrading the quality of the seating (more room for fans), with a minimal net gain of total seats while making the seating sections more comfortable. I realize this plan would have to be phased over time, as the construction schedule would be limited to the offseason, but I think it would be a happy compromise that would appeal to both sides of the argument.
Of course, I'd also have those new, roomier seats, face the infield and not the triangle.
