Columbia changed its zone in the 2nd half to cut off the passes to Bailey at the foul line when he flashed - they dropped one of their top 2 defenders (in the 2-3) to the foul line - causing a couple of turnovers and a couple of other failed attempts to get it to Bailey in that spot.
So RU stopped flashing Bailey, instead flashing Ogbole (who was wide open several times, but RU wisely did not pass it ot him in that area of the floor ... why Ogbole flashed I have no idea!), and Derkack. Derkack received the pass 3 times when he flashed, and was wide open all 3 times. Once he was so wide open he could have sat down and taken the shot from his rear end and no Columbia player could have contested (that was how wide open he was) - but inexplicably passed the ball outside again. Once he shot and missed. Once he drove to the rim rather than shoot. I think Derkack may not have a mid-range game - which means HE cannot be the guy flashing.
RU ALSO changed their zone offense after the Bailey flash was cut off: RU started setting a screen for Williams or Harper against one the "2" defenders in the 2-3, and either Williams or Harper would drive into the middle fo the zone from the top of the key, getting into that open hole in the middle of a 2-3 zone. Williams or Harper would then either pass to an open teammate (Davis and Harper got several 3-point opportunities from those moves), take the mid-range inside the zone, or go to the rim. Additionally, Davis would dribble penetrate into the zone from the wing (not the top of the key), and pass to teammates (Harper or Bailey, generally).
You saw in the 1st half how RU dissected the 2-3 zone: Bailey was terrific with his off-ball movement flashing into the open spots of the zone. He is essentially uncoverable when he flashes like that, and receives the ball 12-15 feet from the rim: That shot is his superhero weapon, and he is deadly from there ... that may be his best and most efficient shot angle of all the various shot-making angles he has.
