We already knew about Sean Desai. The other two newcomers are Aaron Smith and former Eagle Al Washington. All three fit the prototype BC needs: young and hungry for a shot at the big time.
Smith comes from Columbia where he has held a variety of roles. He played college ball at UConn and Maryland. With an Ivy League background you assume he understands the type of player BC can and will recruit.
Al Washington is a name I floated from the beginning. He seems like the perfect fit in that he is young, understands BC and can help provide a little emotion to a team that seemed lifeless at times. Washington was an undersized DT for BC but always served as a team leader and someone who could achieve beyond his physical talents. Since his playing days he's stayed in the BC circle, first as a GA with TOB at NC State and then as a DLine coach with Swepson at Elon.
The coaches leaving were not a good sign, but I think Spaz really did the right thing with how he filled the openings.
