They should certainly try their hardest to get some sort of stadium on campus. Given the Hurricanes low attendance, I dont know if it's worth trying to build something like what Hawaii did this year? Hawaii I think basically added stadium seating to their practice field. I'm assuming Miami has a practice field on campus? Why not just put in some grand stands and build seating upward.
I think the NCAA has a rule to remain D1 you got to have at least 15,000+ seat stadium or something odd like that. I dont know if it is even close to a possibility for Miami to have anything on campus, but having stadiums, especially if they are shared with an NFL team completely deflates the atmosphere. I think the worst is UCONN, they dont share it with an NFL team, but I think their stadium is across the state from campus.
