After reading the article, I think Lavin is saying Harrison doesn't instinctively look for his shot immediately upon receiving the ball, but rather looks to pass to a teammate with an open look or assumes he needs to put the ball on the floor first and create his own shot. To wit: "[Harrison] often premeditates that, on the catch, he's going to put it on the floor, shot fake and try to get to the mid-range, or he's just going to pass the ball.... What we want [D'Angelo] to do every time he catches the ball is put his eyes on the rim and get locked and loaded to pull that trigger, ... Marco did that the other day. We actually need both D'Angelo and Marco to have that mindset when they catch the ball. If you pass those shots up, teams are already devising their game plans to shut you down."
Well I disagree. To me this is just another example of Lavin failing to expel an idea despite forcing air through his vocal cords and moving his mouth. You might as well parse a fart as one of his pre game quotes.
The Bazooka has played relatively well once this year, in what was essentially garbage time minutes. Whereas DH has played well a bunch of times, and many of those while he was the focal point of the opposing defense. He's won a couple of games single handedly. During those performances I haven't noticed any reticence when it comes to shooting. In fact I'd go so far as to say that he has few qualms about hoisting them up and I suspect if Lavin really wanted him to shoot more or faster all he'd have to do is ask. A somewhat less efficient way to get him to do that is to instruct him to study Marco Bourgault's scintillating 100 minute Division 1 career.
Lavin is an airhead. There's no other way to say it. He's dumb. Fortunately basketball isn't hard, so being dumb isn't fatal. And in fact, since many very successful coaches are utter nice persons - Jim Boeheim and Bobby Knight spring to mind - it may be that being not very bright is a positive coaching attribute. But you'd be better off looking for insight in a blow to the head than in any of his press quotes.
