College Park is in the heart of one of the most populated areas in the country.
For me — and again I’m not a football player — that’s a selling point versus spending 3 years in the middle of the mountains in central PA.
I guess I'd rather play in front of a rabid fan base of 100k plus fans in a rocking stadium for a relevant team.
The only reason I can see for rather playing at Maryland is if you want to play close to family and friends.
