He was completely nonexistent during that stretch when he was playing instead of Babb and was out there with KL. Babb is better in almost every facet of the game than Bubu, and by a large margin.
Bubu has had two or three times he's been dribbling with little to no pressure where he almost double dribbled or lost it. He is not very comfortable out there, and Jackson noticed it and tried to take advantage.
I like Bubu. He is more than what you'd expect from a walkon and usually doesn't play outside of himself, but he doesn't bring much to the table on offense. Babb being out there would've been more productive in my opinion as he's better than Bubu at just about everything when you consider Bubu was playing the 2.
