Depends on seating capacity of the new arena. Schools like Duke/UCLA, etc., command huge appearance fees to play at mid-majors in N-L games to show off a local player. If memory serves, Syracuse had an Albany-area player (Craig Forth) on the team, the starting center, during the time of Carmelo Anthony's one season. Syracuse, only about 140 miles away from Albany, agreed on a 4-for-1, with the one game in Albany at that city's 15,000-seat arena. Syracuse reaped a $200,000 (reported by local news outlets) guarantee to come to Albany to play the game. Tickets were vastly overpriced and only 8,200 attended. Albany barely broke even on the game.
If Duke, or some other ACC school eventually gets Flagg, the likelihood is that closest it will come to Maine will be games at Boston College.
