Obviously, we need to look at where we are as a team to determine what to do with Randle. With the emergence of Rivers and Quickley, PG may be far less of a need than originally thought.
The ideal player to add to the Knicks team is Kawhi Leonard - a 29 year old 2-way wing that does a lot of things at an elite level. But unless he goes to Ballmer and says he wants out and wants to specifically go to the Knicks, I don't think he'll ever end up here.
Randle is pretty much the ideal age (26) for a young superstar addition and for now, is producing like a $40m max-type player. We're very fortunate to have him at 2 years at basically half that price. He may indeed not be a true #1 option, but I don't see where we find a clear upgrade in the 25-30 age range. You can't really go much older than that, because the rest of the team is basically made of 20-22 year olds that are still finding their games.
The Knicks imho could use a better 3&D SF and PG - Basically we see opportunity for much better play from Bullock/Payton's minutes. I think both of them have fine contracts for what they give - at least we're not overpaying them.
Quickley and Rivers might already be the guys that take over those minutes. The Knicks would have to be comfortable with RJ taking the physical punishment guarding somewhat bigger players at SF.
If we're looking at a more traditional lineup, we probably can get improve at PG with either Quickley/Rivers getting the bulk of the minutes running point, and Frank/Knox/Obi stepping up.
I think what we will probably end up seeing is Randle sticking with the Knicks and some of our young assets moving on for mild upgrades. Plus we have 2 first rounders coming next year.
