You make very valid points but it is also a catch 22 situation. Mason is still learning the system and we still see him make bonehead plays and the best way to learn the system is to play more. So, you want him to play as much as possible so he can become more familiar with the system while at the same time you want him to play less to conserve energy.
I am not convinced that Svi is the answer. The game is still playing very fast for him and has not slowed down and thus we have seen reduced playing time. At the PG, the game would be even faster and I am not sure he is, at this point, at a level where he could handle it; he is not a natural PG and his natural position, at least in college, is SG or even SF; in the NBA he will likely be a combo like Hinrich or like Chalmers become a PG. No doubt that he has the natural skills and basketball IQ to adapt to the position but again, do you take a hit at that position while he learns to play it? I am sure he would do fine at the slower Euro pace, but at the faster American pace, he would be, at least initially, at a disadvantage. Just my 2 cents…
