This was a RIVALRY game (the one game that you circle on the calendar every year). Whenever your biggest rival comes to town,
you go to the game. Since the UConn/Tennessee WBB estrangement, ND has become UConn's biggest and most serious rival. Ask
Skyler Diggins/Bria Hartley if they could only beat 1 team during the season, who would it be. The reverse is also true. The Irish does not have any trouble selling tickets in South Bend when UConn comes to town.
The game is usually sold out the first day the tickets go on sale in South Bend. That game is the local scalper's biggest WCBB game day of the year. People that failed to get their tickets early, will begrudgingly pay extra for the privilege of attending the game.
This game was also the first chance many of the locals had to see the newbies and transfers in person. They knew this game had all the earmarks of a great game, and they wanted to be part of it. Where do you think this game will be played in 2019 when the Irish come to town once again?
One more observation - 15,000 fans in attendance at any UConn home game is very impressive to any potential recruit(s) that may be in attendance, and also let's the coaching staff know they're doing something right!!
