It may have been Starks, perhaps Gilder, who was doing their best to break Sexton's "path" as he was dribbling. They didn't. Personally, it was drawn up the exact way I would have done (and I'm no where close to having the same basketball IQ as any collegiate HC.)
They had guys on the court with four fouls. What do they not want to do? Cheap foul (within the arc that's two, outside we're looking at three attempts if he's shooting.) They didn't foul.
When they forced Sexton to take the inbounds around the line they immediately fell back to cover any lane he'd have to dump off, right? The point wasn't to keep him from getting the ball but to slow him down (hopefully around mid-court) and more importantly NO FOULS.
I've not watched the replay again, but I'm sure they slide a man over (#2 or #3) to slow him down and not allow him to run the court. LIke their coach said, their goal was to stop him from baseline to baseline. When he kicked that "extra gear" in around the half-court line there was no option outside of fouling; they weren't going to catch him.
CAJ has said on a few occasions that Sexton was the fastest he's seen from baseline to baseline. Coaching speak? Perhaps. There's no denying the fact he's very fast with the ball.
As much credit as Collin has due for an amazing play it's simply illogical to me to say "bad coaching" when they played it ideally. I see too many "let's have it two ways" with this team and this seems like another prime example. How different is what we're talking about to the narrative we've seen pushed...
Bama has no offensive sets versus Bama is missing a lot of open looks.
