Also I think OG is bette than Mikal and if I was the Knicks and it came down to offering OG a crazy contract or trading away 5 picks for Bridges I would most certainly prefer the former.
OG is not better than Bridges. First, Bridges plays 82 every year while you are lucky to get 50 out of OG.
OG is maybe a better defender and more atheletic, but Bridges is better offensively and the defensive difference is minimal.
Over their careers . . .
OG
.098 WS/48 (league median for players that qualified last year was .106)
+1 net rating
13.1 PER (league average is 15.0)
Bridges
.113 WS/48 (0.70 last year)
+6 net rating
14.5 PER
A case could be made that both guys statistically don't contribute enough across several categories, and the things they do well don't make up for the things they don't do well. I know the Knicks had some crazy numbers with OG on the court after the trade (20-3 record with a +22-point scoring differential). Clearly, the Knicks would be better off with both of them on the roster and both healthy (vs. the guys that were filling in due to injury).
Randle career numbers:
.101 WS/48 (.105 with the Knicks)
-2 net rating
18.1 PER (18.5 with the Knicks)
Randle is probably more valuable than either OG or Bridges, but who knows if they want to pay and keep all of them. Randle essentially is on an expiring contract (has a player option after this season and would make way more by opting out). New York can offer OG 5 years and $245.3M. Not sure he's worthy nearly $50M a year (and whether the Knicks would go that high). Other teams could offer him 4/$182M.
