Looks like a pretty straightforward pass/layup to me: I dunno maybe it got knocked out of his hands by the off-balance defender but it didn't really look like it.
These guys just have bewilderingly bad ball security at times. Outside of TH, I had very little faith in any of them dribbling in traffic in this game -- and that would include IB in this situation. With that officiating crew, there's no guarantee that a foul would've been called before the ball was stolen. Second-guessing IB's decision to make a fairly routine fast-break pass is just armchair quarterbacking.
Agree this should be routine for players at this level, but just seemed unnecessary given the circumstances. There were two guys on that break and he’s going full speed throwing pass across his body. One defender nearly got a hand on it. There was really no need to try to get a run out right there except to get away from defenders and eat clock. You don’t need a bucket right there.
