Will a new scoreboard increase attendance?
Probably not directly. Attendance is driven by winning more than anything else.
Possibly. Every MAC arena I've been to (all but a few) has a better scoreboard and video system. If you think prospects don't notice, you're wrong.
Better recruits, better results.
I don't think this is transformational by any means, but it is so long overdue and the past system was such a letdown for the fans, building and programs that use it that I don't see a lot of value in lamenting a $2 million price tag. I'll add that it will significantly enhance graduation ceremonies, women's hoops, volleyball games, wrestling matches and every other event that takes place there.
