Yeah, it's weird all the posts I've seen talking about how much more hitter-friendly the ballpark is going to be, ignoring the extra height of the fences.
The team may turn out to be wrong that it's a neutral move but simply moving in the fences does not mean a kajillion more homeruns if you're also making the fences taller. I think that's obvious?
And per some of the fine discussion here, yeah, no one decides not to go see their local team because some other team across the continent has a better stadium or arena. The Raptors are allegedly #4 in attendance right now, despite a bit of a horrorshow of a season (and despite the age of their arena). The 3 teams ahead of them (Dallas, Chicago, Philly) have arenas of a similar vintage, and 3 of those are a bit older. It's almost like that's not a big factor in attendance or profitability?
Anyway, the Jays will likely get a nice bump this year from people at least wanting to check out the new stuff; all the moreso if it gets "good reviews." I'm looking forward to seeing it in person.
