PG maybe more than any other position will usually be attracted to a coaches style. For instance, Calipari runs a system that will always be attractive to PGs. same with Pitino and Williams. I am surprised Mike Anderson doesn't get better PGs, though he does have great backcourt players in Durham, Bell and Hannah's. High usage, sometimes up-tempo, lot of dribble drive, lots of possessions.
It's also the reason Mfon Udofia never made it in Atlanta. Played up tempo for 4 yrs of HS and comes and plays in the plugged toilet offense and then Gregory's for a year.
Slow it down grind it out styles are rarely very attractive, UConn would be the exception not the rule and the reason for that is Ollie, like Calhoun, has the ball in his PGs hand a crazy high % of the time.
It seems like with the decline of the NY PGs the amount of hard nosed, slow it down, defensive PG has become less common as well. I think Kemba Walker is the only NY PG in the league.
