You're reacting a bit to the slomo replay. Samuel did a good job and cut him off as he tried to drive - but after there was some hip-to-hip contact, the Terp guy stopped and popped as the bump knocked Samuel off stride a little. That's a tough play to get your momentum going back forward to contest - especially when you're young and haven't gone through all the agility drills with chairs and cones to get your body trained to change direction on a dime. Best you can do is sort of wave your hand in the air while nailed to the floor, but you won't get in the shooter's field of vision. A Ricky Moore type might be so agile that they can spring back instantly and not give that shot up as easily, but those guys are hard to come by.
The issue with needing Boat out there, especially without Bazz, was better seen when Samuel had the ball poked away with 20 seconds left. It just went o/b, but you need better ball toughness there when the other team is going to be gambling and poking at it.
If Uconn team wants to go deep this year, it should become clear to KO that a 3rd reliable ball handler needs to be brought along. I think it's better to start now.
Here is what i see the issues with Boat (don't shoot me for saying)
It's a fact that Boat's height is an easy exploit, especially when the game gets tough.
Facing a taller opponent with equal athleticism, what will happen? Boat become a liability in both offense and defense.
However, this is not fatal, a smart player can make it less vulnerable. Kemba is a weensy-teensy taller, but he use his quickness and cunning skills to hide or cover that.
This leads to another of my worries. His basketball IQ is not there or he is not using it to make up for his height disadvantage. Kemba made a quantum leap from Soph to Junior year. In this game (yes one game) , I don't see he is reading the opponent, learning the game, adjusting his plays accordingly. Again, one game in the season start does not conclude my analysis, and I hope to God, it's NOT!
