So why is that when Nick Van Exel and Damon were on the team they'd run the pick and roll to death with Joel and he did pretty good at it? Nate comes in as the coach and all of that stops; none of our bigs gets the ball on rolls to the hoop in any kind of consistent way.
My opinion is that we look at those times through rose colored glasses. Last year Joel's TS% was significantly better than what it was during that time, his TOV% was lower - and it was done with a lower usage%. He was used super efficiently. Sure, he might have had better scoring nights than - but if they were not efficient - why is it good?
This year, so far, being on the same unit as Miller - who is trying to incorporate him - Joel's TOV% is at an all time high... last year - it was at an all time low. Any way you look at it - Joel is a high TOV% guy - he is over 20% for his career.
Boozer, who is a good PnR target - and is used twice as much by his team as Joel is - is at 12.7% for his career. He can catch a ball on the move, absorb contact, protect the ball doing it and finish. Joel is simply not good doing it.
Joel is not a good PnR target - he does not have the hands for it, period, and when he is fouled - he does not convert his free throws efficiently. You want to believe it was done great with the Van Axle/Stoundamire combo - go for it - but the cold, hard data shows us that Joel was most efficient when playing next to Roy.
As to the larger point, asking Brandon to play off the ball and receive the ball on the move or off of a pass isn't exactly marginalizing him or asking him to take a reduced role in the offense, it's likely getting him the same number of shots but theoretically making them easier. Sure Roy is going to be the primary ball-handler late in games and there will always be times when he can exploit a mismatch with the ball in his hands, but the idea that a shooting guard of Brandon's hoops IQ can't find a way to coexist with a point of Miller's skill seems a little crazy to me.
It is marginalizing him if the guy that handles the ball is not better than him running the offense, which Miller is not. The reason it worked so well with CP3 in the all-star game is because CP3 is one of these great point guards that appear once in a generation. Brandon Roy is a better decision maker than Miller. If Miller had the same advantage over opposing point guards that Roy has over opposing small-guards when he controls the ball - it would make sense, since he is not - I suspect this is going to be more of an issue than you want to believe.
If KP had gone out and signed another ball dominant one on one scorer I can see why there should be a tug of war going on with the ball, instead this seems like a wasted opportunity to get him easier looks. Who knows, maybe Brandon just sucks that badly off the ball that he can't hit open shots off the catch or he can't cut off of screens or make backcuts to the hoop to receive lobs from Miller on the break.
Brandon is not a motion off the ball kind of guy like Reggie Miller, Rip or Rudy are - his biggest asset is being able to impose his pace on the game. Again - I am sure Brandon can and should get better in these aspects of the game - but you are taking him away from his biggest advantage and forcing him to adjust to a guy that should really be a role-player. These things do not often end well, in my opinion. If you do not believe me - see what happened to Nash when they brought him a big role player in SHAQ that marginalized his advantage.
Time will tell.
