Hartford needs a new arena or a very new model of the current arena. Period. If they want to make UConn the main tenant (like Raleigh, NC did with NC State), that's fine. Let the Wolfpack walk and then let UConn keep a good chunk of revenue generated from gamedays for hoops and hockey. It only makes sense for UConn if they can keep money from ticket sales and some of the concessions. They appease their alumni and fans who don't want to drive to Storrs on a Tuesday night by playing games more centrally located. It makes sense for Hartford regardless because UConn gamedays/nights are really the only days/nights that people voluntarily go into downtown Hartford and spend money.
Either way, UConn needs to, at the very least, build a Champions Center type of facility on-campus for hockey. Whether it includes 4K seating for a handful of weeknight on-campus games or not, it should include state-of-the-art training, nutrition, meeting rooms, coach's offices, study halls, etc. That is very much needed for recruiting and player development.
The negative perceptions that UConn is tagged with over football recruiting territorial location do not apply to hockey one bit. We are smack dab in the middle of one of the richest areas for youth hockey. With our AD budget, brand, size and student body/alumni numbers, there is no reason why UConn can't emerge as a national hockey power fairly soon. But to make that happen, an on-campus facility is an absolute must.
