Seriously though a 10k seat arena? What?
Excluding the big Northeast cities and assuming that Hartford will not get an AHL team, a 10K arena appears to be preferable size venue (hockey seating) for a mid-size metro areas in the region in conjunction with AHL average annual attendance (2014/5).
1) Portland ME (625,000): Cross Insurance 6,700...Attendance: 2,800 (AHL)
2) Manchester MH (400,000): Verizon Wireless 9,800; Attendance: 5,000 (AHL)
3) Worcester MA (900,000): DCU 12,200; Attendance: 3,500 (AHL)
4) Springfield MA (700,000): MassMutual 6,900; Attendance: 3,000 (AHL)
5) Providence RI (1,600,000): Dunkin Donuts 11,100; Attendance: 8,000 (AHL)
6) Hartford CT (1,500,000): XL 15,600; Attendance: 4,000 (AHL)
7) Bridgeport CT (900,000): Webster 8,500; Attendance: 4,500 (AHL)
8) Albany NY (1,100,000): Times Union 14,200; Attendance: 3,200 (AHL)
9) Syracuse NY (740,000): On center 6,100; Attendance: 6,200 (AHL)
10) Rochester NY (1,200,000): Blue Cross 10,700; Attendance: 6,100 (AHL)
11) Buffalo NY (1,200,000): First Niagara 19,000; Attendance: 18,400 (NHL)
12) Newark NJ (part of NYC) Prudential 16,700; Attendance: 15,100 (NHL)
13) Scranton/WB PA (560,000): Mohegan Sun 8,000...Attendance: 5,300 (AHL)
14) Allentown PA (830,000): PPL 9,000...Attendance: 8,000 (AHL)
I just don't see an economical reason for an arena in Hartford of higher than 10K based on these numbers. Does UConn draw more? Of course. But, UConn's needs are different that Hartford's.
14) Pittsburgh PA (2,700,000): Consul 18,300; Attendance: 18,600 (NHL)
