To be fair, that clip is showing a vertical-angle cell phone shot that cuts the defender out. Prior to this, while Shammah was dribbling the air out of the ball near half-court, the defender was on his butt. The defender not shown in this footage was actually at or a little beyond the 3P line. Shammah hit that stepback from Canal Park essentially which is exactly what Toledo wanted. Akron wasn't shooting the 3ball well all night, they kept the Zips out of the paint by design on the last possession and gave Shammah a contested stepback 3 from WAY downtown. He hit it and the rest is history. I don't think they'd ever change their game plan except for maybe try to force the ball out of Shammah's hands, although I don't know if they fully expected the ball to stay in Shammah's hands the entire possession.
