MacCormack, a senior committed to Syracuse, deflected Tabor quarterback Peter Bourque's pass in the end zone as the clock flipped to zero.
MacCormack's Herculean effort propelled BB&N to a dramatic 28-22 victory over Tabor in a contest between the top two teams in the ISL7. The Knights (7-0) have clinched at least a share of the division with one regular season game remaining.
"I thought that they were going to spike it," said MacCormack. "I didn't really know what they were going to do. They ran a play and he kind of threw it right over my head. I looked back, I saw it was on the ground, I checked to see if there were zeroes [on the clock] and it was and I went crazy."
MacCormack started the game with an equally impressive highlight, cutting back a zone run to the left side and beating the defense to the edge for a 59-yard touchdown on the Knights' first offensive play.
"He's gotten better and better and just when I think he can't get any better, he gets better," said BB&N coach Mike Willey. "He just kept working. He's faster, stronger, and bigger every year."
MacCormack posted eye-popping numbers running behind the offensive line of junior Tim Church, senior Nate Bodden, sophomore Liam Cunningham, sophomore Ben Pantera, and junior Jake McGrath.
MacCormack's blend of breakaway speed, quickness, strength, and vision were on full display. On his third TD of the game, a 15-yard score, MacCormack barrelled over the safety, throwing him to the turf with a punishing stiff-arm.
"Bo MacCormack, there's not enough adjectives, not enough superlatives," said Willey. "Bo MacCormack is in a league of his own. Obviously a great player, but watch him be a teammate. Watch him in the weight room. Watch him in class. That kid is an unbelievable kid who happens to be an unbelievable football player."
Special teams coordinator Howie Rock dialed up an onside kick to start the second half, which Ellis Barnes recovered for the Knights. The BB&N defense did its part after halftime, as Will Volk stripped Bourque on a scramble, which Vince Sloonian pounced on. Two series later, Colin Hoffman ripped the ball away from a receiver for an acrobatic interception.
