Not a fan of Ibaka, however this is the framework of move that makes some sense (albeit not this one directly). I have never been high on Chriss, but im not sure giving up on him for Ibaka does much.
Ibaka doesnt protect the rim anywhere like he used to, doesnt hit the defensive glass anymore, doesnt hit the offensive glass anymore, doesnt generate turnovers, and basically has transformed himself into a stretch big who doesnt shoot it all that well.
Context?
Ibaka has been in the 75th+ percentile among all bigs in 3PA each of the last four years, yet his eFG% has not risen above the 65th percentile. Not to mention, hes one of the league leaders (among bigs) in long mid-range jumpers attempted, basically his entire career. Add that with not having been in the 50th+ percentile on the offensive or defensive glass among bigs in that same time frame and...
No thanks.
