The thing with Okafor is not that he is injury-prone. I don't think he suffered more injuries than a typical big man. The problem is that he is notorious for unwilling to play with injury, major or minor. He does not suit up unless he is feeling 100%. Not 90%, not 95%; it has to be 100%.
Even when he is healthy, he doesn't play until he himself is sure he is indeed healthy. It's been reported that some of his teammates are beginning to question Okafor.
I think Okafor is one of those guys who will continue to miss games throughout his career. It's his personality. If a guy doesn't like to play with nagging injuries that's the way it is. You can't force him to play. Now, the last two seasons where he played in all the games, that's half blink luck and half common sense, imo. It's not unusual for an injury-prone guy to stay healthy for a short period after missing significant time due to injuries. It's because they came back fresh and healthy. But after a couple seasons, they revert right back to their injury selves. Except, in Okafor's case, it's not really the injury that's going to keep him out but his mind that's going to stop him from playing.
Furthermore, Okafor needs starter minutes. He is much more effective that way.
In other words, if the Kings get Okafor, they're essentially giving up on Hawes for an overpaid, oft-injured, and undersized center. If money is not the issue I'd love to have Okafor. But at at his price, the only logically thing to do is pass.
Let's say Okafor comes aboard and plays to his normal self, does that make us a champion-calibre team? No. Playoff team certainly but not a championship team.
However, if Okafor instead becomes the man who misses 30-60 games then this team is screwed. We're stuck with a half-performing cap killer for the next half decade.
The risk to reward does not make sense. It just simply doesn't. We need another big sure, but not one who is overpaid and with a history of missing games. When the trade deadline comes, I'm sure his name will come up again. The smart thing for the Kings to do is to take a look at Hawes and say, "No thanks. Our center may be a weenie but at least he plays thru injuries, is not undersized, and not overpaid."
