Rooms are now available since we're within a year of the game date, but many close to the stadium are already sold out. I got a Holiday Inn Express 1.7 miles from the stadium for $157/night.
I wouldn't recommend the hotels "close to campus". I'd suggest the short north area and to be quite honest it's walkable.

Lots of non chain restaurants, breweries and very cool bars around the convention center and in the short north.
Happy to answer questions about fun places and suggest food and beverage.
