The kid had more turnovers (1.5) than assists (1.3) last year. Granted, Ollie has proven over a limited sample size that he has the ability to improve the skills of his PG's drastically from one year to the next, but PG is the one position I'm simply not comfortable transitioning players into, simply because it's a position that takes so long to master. Being a PG is similar to being a QB in football - there are so many various factors you have to account for in merely one play that kids who are unqualified to play the position have the tendency to become overwhelmed. Even kids like Ryan Boatright and Shabazz Napier - who have played the position their entire lives - struggled to adapt to the accelerated pace of the college game in their first couple years. The poise, savvy, and seasoning required to play the position isn't something I believe you can acquire in one or two years, even under the tutelage of an NBA veteran. And the development of PG's have a direct impact on the development of the entire team - if Purvis struggles in his innaugaral year at the position, he won't simply struggle in a vacuum, his teammates will also struggle. Exhibt A: Kemba Walker and Jerome Dyson struggling to co-exist in the backcourt in 2010.
I'm certainly not opposed to gradually developing him at the PG position (i.e., 10-15 minutes at the one in his first year, then maybe he can man the position full-time in 2015), I just think throwing him to the wolves in year one, when he won't have played a legitimate game in 20 months, is a risky strategy.
