i would trade them for Syracuse in a heartbeat, only to get rid of the NYC influence on the ACC
with that said, Maryland will never be welcomed back to the ACC. They were in the ACC for over sixty years and when there was smoke about them going to the Big Ten, they didn't even bother returning any of the ACC's phone calls.
I doubt Maryland is interested in returning. Big Ten money is too good + they always whined about how North Carolina-centric everything was. They were full of shit about the latter, because when they finally bailed, the new talking point was with the additions of BC, Syracuse, Pitt, etc, they no longer recognized the ACC. LOL. tbh, I've always viewed Maryland as a school with an identity crisis. They don't know who they are.
