In terms of Rudy Gay, I think he should just be traded. Let me be clear, playing Rudy at the 4 is a better fit than an out of position center. But that doesn't change that Rudy should still be traded.
Whether the more extreme comments in
http://www.sactownroyalty.com/2016/7/26/12283364/sacramento-kings-rudy-gay-frustration have been partially walked back or not, its clear its not a great place. And keeping the chemistry good after years of bad chemistry would seem imperative at this juncture.
But more than that, Rudy Gay isn't a great fit on the Kings and is an expiring contract who doesn't sound like he wants to be back. Thats when you trade a player if ever.
Here are some fun potential Kings sf stats:
Matt Barnes
32.2% 3 point shooter in general.
33.8% When catch and shoot
29.1% When wide open (6+ feet)
Rudy Gay
34% 3 point shooter in general.
33.5% When catch and shoot
34.3% When wide open (6+ feet)
Garrett Temple:
34.6% 3 point shooter in general.
35.2% When catch and shoot
39.3% When wide open (6+ feet)
Anthony Tolliver (okay this one is a pf)
36.0% 3 point shooter in general.
36.5% When catch and shoot
42.5% When wide open (6+ feet)
Afflalo
38.2% 3 point shooter in general.
36.6% When catch and shoot
42.0% When wide open (6+ feet)
Casspi
40.9% 3 point shooter in general.
38.6% When catch and shoot
42.5% When wide open (6+ feet)
Compared to the other options (Okay minus Barnes), it would seem clear that Rudy Gay cannot capitalize on the easy high efficiency shots that playing with Cousins should generate.
Gay's big strength is that he can generate his own scoring, but unless he is being used as the bench scoring punch (which would be ideal), then it is a skill set that isn't getting maximized. As to whether he is a 3 or a 4 more naturally, I think he is in that sweet spot that depends entirely on rosters of both teams playing.
How much worse would Sacramento be if instead of Gay playing at the 4 they used Casspi and Tolliver? Instead of Gay playing at the 3 they used Casspi, Afflalo, and even Temple?
I see a very small fall off if that, and meanwhile whatever they get from a Gay trade could strengthen something else. And again I circle back to that Rudy Gay isn't a great fit on the Kings and is an expiring contract who doesn't sound like he wants to be back. Thats when you trade a player if ever.
