I wouldn't go near that high/long for Randle.
But IF NYK signed Randle for $22M, then I wouldn't give Vonleh $8M to back him up. That's $30M committed at the PF slot without either of them able to really fill in as a smallball C. And PF's are not as important as they used to be.
My attention is on -- and Knick $$ should be spent on -- getting a starting PG and a 3&D SF who can guard multiple positions. That's where I'd overpay/use cap space. If not available this year, I'd hold off and roll over cap space.
I'd be fine going with say Vonleh and Richuan Holmes at PF for a combined $12M or whatever. Or extracting something from POR and taking on 2/$20M of Meyers Leonard, so they can avoid luxtax. My Leo always looks pretty good to me. Sets screens, can pop 3's okay, boards allright, will mix it up. A bit chumpy on D, in the Kanter mold.
I'd be looking to be creative, keep options open, use cap space wisely, and above all be patient.
