Looks a bit empty to me...it's also intermission.
There aren't 10000 people hiding on the concourses during intermissions in Columbus, though. Ohio State hockey rarely draws higher than 5000 in a 17.5K seat arena, which they need because they get over 16K for hoops.
I cite Ohio State as almost the perfect object lesson for what we can expect hockey attendance to look like either using the XL Center as our long-term home, or in a newly-constructed hybrid basketball-hockey arena on-campus (Gampel is a non-starter for conversions): solid numbers, in an arena built way too big for that purpose, which make the overall fan appearance "empty".
UConn hockey is unlikely, even at its ceiling, to draw more than 1/3 the attendance of UConn basketball of either gender. I would *love* to be proven wrong, but the numbers don't look good for us. What that also means, beyond the empty look of the arena, is that we are going to be forced to put hockey games in time slots that aren't the *very* traditional Friday & Saturday at 7. Look forward to a lot of Saturday and Sunday afternoon games, and I would wager at least 2-3 Tuesday or Wednesday nights a year.
Then, we get into the problem of ice time. UConn is going to have to build a second ice sheet on campus anyway for practice because they're trying to fit in the men's team, the women's team, the EO Smith/Tolland/Windham co-op, and the Northeast Icedogs; at that point, the utility for having two ice sheets, one of which is constantly being used by a basketball team, diminishes (not to mention the expense of maintaining two ice sheets, especially if the two are physically dislocated from one another and the school has to maintain *two* refrigeration units).
