When I came to Drexel in 1991, SJU was the only B5 team to play Drexel regularly. SJU even came to the DAC in 92-93. They were also the only B5 team to play Drexel during the Malik Rose era, other than when they faced Temple in the NCAA Tournament. The Battle of 33rd Street didn't begin until after Malik graduated. Also, the DAC is now much less of a crappy little gym and now more of a high quality boutique arena. The facilities are much nicer now. Also, now that the students are further away from the court, there's less of a home court advantage for Drexel. Additionally, there's basically zero travel costs for both teams with a home and home. So considering all of these factors, I can't see why they wouldn't continue to play Drexel every year.
