I think criticism of the coach is fair.
There is plenty of talent on the roster. Phil Greene is perfectly serviceable at the point. Branch does some things very well, though he also has some weaknesses to be worked on. Between the two of them, the PG spot is certainly adequate for the Big East.
Harrison is obviously as good a 2-guard as there is in the league - at least based on talent. More about him later.
Obekpa is not a finished product, but is already a game-changer as a shotblocker and is coming along as a rebounder. Obviously his offensive game needs work, but he is still a guy just about any team in the league would take and start at center.
Sampson is obviously a talent, and Garrett is a great energy / glue guy who does positive things all over the court.
On the bench Pointer, Balamou, Bourgault are fine role players (though one wonders exactly what role Bourgault has - you would think he is supposed to be a spot-up shooter, but somehow he never gets to do that).
And yet all of these pieces don't seem to fit together. There's no identity on offense, they don't seem to know their roles, there is no rhyme or reason to the substitution patterns. The only visible play is a high pick (usually without even a roll), after which the offense consists of getting the ball to Harrison and hoping he will create something.
Of course everyone has figured that out, which has mostly reduced Harrison's offense to driving and getting fouled. There's no ball movement, and no man movement either. It's arguable that Norm actually ran a better offense.
Some of this is attributable to the fact that only Green, Branch, and Harrison are actually basketball players. Presumably so is Bourgault, though he never gets to play enough to know. But it is clear that the rest are athletes who are supposed to be learning how to be basketball players.
It's obvious that the philosophy is to try to create turnovers out of the zone (not working) and then run the floor for opencourt baskets. That's good, because at the moment running down the floor and dunking is the only thing this team does well. The problem is that (a) the zone isn't working and (b) there is nothing going on the halfcourt offense (I use the term loosely). It's not just the Georgetown game, it's every game. The wins have just papered it over.
At the end of the day, if the players still can't operate the zone, if the staff waits until they are out of the game to switch to man (as in the Georgetown game), if there is no apparent halfcourt offense, and if the ball gets forced to Harrison while all of the other players stand around, if there's no team identity, they don't play together, and they don't know their roles, there is only one place to lay the responsibility.
All of it is fixable, and experience will help. One would have to think that the staff sees the obvious, which is the first step towards fixing it. But they may have to make a decision whether they want to continue trying to make Harrison the next Dwight Hardy, or whether they actually want to run a team game.
But right now it's tough to watch.
