A quick note about that- Curry has limited tools that hurt him when defending wings, but he was very good at defending PG's.
He held opposing PG's to a 9.8 PER and an eFG% of 43.9 which is outstanding (for reference Temple held opposing PG's to 12.2 PER, which is also good).
These numbers changes dramatically when he had to defend SG's who he held to 15.7 PER and eFG of 53.5%.
So I think he can do a very good job against PG but struggles defending wings.
I think Curry is an overall below average defender. However, he does a much better jobs on PGs than SGs. A lot of his defense comes from his gritty and pesky play. He can put pressure on the ball handler without fouling. He's disciplined, and that's why he looked good through the eye tests. He wasn't scared to put a body on the opposing PG. Seth's problem is that he's light, short, unathletic, and slow.
Whether anyone likes it or not, I think it's pretty clear that Ben is our best perimeter defender. Right now, he's about an overall average defender. His biggest problem is that he gets lost at times. Ben has a decent build and he's a great athlete. I think if anything, hopefully we'll be able to see Joerger tap into Ben's defensive potential like Malone did. It's looking a bit unlikely since we brought in Afflalo. Seems like Ben will come off the bench, and is probably gone after this year.
I don't blame Gay.
Here are teams who would probably be interested in him: Rockets, Clippers, Pelicans, OKC, Bulls, Pacers, Heat, and Wizards.
Out of those teams, only the Rockets, Pelicans, Bulls, and Wizards would have decent assets to trade.
Rockets: Beverly+Brewer. I would say no to this trade. Beverly is a fringe starting PG who's 3&D. Might be good for Cuz, but our 2nd option would be Afflalo...that's terrible. He could've even crack it as NYK's 3rd option. Brewer is washed up now and he provides nothing positive except "vet experience". I don't know that they'd be willing to pony up Ariza.
Pelicans: Tyreke+Pondexter. This is probably a very good trade for us. Tyreke can play PG here, while DC plays SG on offense. Pondexter was a 3&D player before his injury, and he'd fit great alongside Cousins. The Pacers just added Hill, but they lost a ton of scoring in Gordon/Anderson. I think they need a real #2 option alongside AD.
Bulls: McDermott+Portis+Calderon. This isn't the best trade, but we get young players back while fixing the hole at PG.
Wizards: Morris+Oubre. Buyers remorse? I think this is another trade to think about. Morris has 3 years left on a very good contract. If things don't work out with Morris, we get a young SF in Kelly Oubre.
