The problem with shot distribution can be attributed to experience. Low experienced players won't make the best decision and might shoot instead of dishing off to the big. Also good defense can force your team to take awkward shots. Maybe your guards were high before the game, the possibilities are endless.
But the problem is not the quality of shots. If you check FG percentage, quality of the shots were good, and also nearly all of them were 2 pt shots - most of them are from paint. The problem is; why did my small guys took those high quality shots, but not my tall guys ?
In any tactic, if the quality of a shot is above a certain threshold, the player will take it. The tactic selected will adjust the required quality - a SG may fire up a relatively lower quality three when in a Run and Gun, while passing it up when possible in a Look Inside. Guards often in inside offenses will cut to the basket, and a good pass from the big man may lead to a fairly high-percentage driving shot. In theory, a guard with good inside shooting skills may even post up a less-capable defender, and I think I've seen anecdotal evidence to that effect but wouldn't claim it to be anything more than a theory.
In any case, the tactics tell the players how to move about the court and where to move the ball, but they'll still make decisions based on their likely percentage to hit a shot vs. the likelihood of completing a pass or drive. And occasionally, you'll have guys that just like to shoot contested long-range 2 pointers even though they never make them because you dared to question the match engine. ;)
