This year Hayward and Green have similar roles ...
Um ... no.
Hayward is playing SG and is one of the primary ball handlers on his team. He averages 70.8 touches per game and has possession of the ball some 3.4 minutes per game. He averages .23 points per touch. He scores .26 points per half-court touch.
Green is playing SF, is used almost exclusively as a finisher on offense. He averages just 46.7 touches per game and has possession of the ball just 1.6 minutes - less than half the time Hayward has it. He averages .34 points per touch. He scores .43 points per half-court touch.
They are both very good players, but they are not at all in similar roles.
This is true, but I think it's worth pointing out that I don't think Green could or would want to function in the role that Hayward is playing right now.
I mean, if there was ever a time for Green to take a larger role in terms of getting more touches on offense, it would be this season. It hasn't happened. I just don't think that's the kind of player Green is or wants to be.
I don't try to guess what any of these players 'want'.
I think it's pretty obvious that Green is playing in a team and an offensive system that goes as it's point guard goes.
When Green has been on the floor with Jordan Crawford, he has averaged 0.381 FGA per minute, or 0.194 FGA per possession.
When Green has been on the floor with Pressey, he has averaged 0.474 FGA per minute, or 0.251 FGA per possession.
That's a 30% increase in shots for Green when Pressey is at PG versus when Crawford is at PG.
Note that Green's eFG% is virtually identical with either Pressey (48.9%) or Crawford (48.4%). So again, as I've mentioned before, increased USG has not resulted in decreased efficiency for Green.
