I can think of several reasons not to bring Diaw back in so I'm not wholly convinced we should sign him. The main reason that I would push to bring him back in though is if they felt he could play alongside Gortat. Frye is just killing us, especially on the road and I just can't see Diaw playing any worse than Channing has been. If Frye is hitting from the outside, you leave him in there but if not you let Morris and Diaw have his minutes.Steve
The major problem with Boris Diaw is that, no matter how good his team is, there is always going to come a time when they get put to the test. If we're a bubble playoff contender, it's going to happen maybe 9 or 10 times during the regular season (82-game sched), and if you're a real championship contender, it might come in every game from the start of the playoffs until the final buzzer sounds. But during those moments, your five guys are going to need to take it from the other five guys. That team you have needs to be the aggressor; when the action picks up and the speed of every movement gets kicked up a gear (even the the pace may slow down, but people's muscles are moving as fast as ever), and with Boris Diaw, you're going to lose a lot more of those battles than you're going to win. Now look, there will be times when Doris gets the ball in a position where all he really needs to do is try to score with an acceptable amount of aggression, but instead he kicks it out to a guy on the perimeter for a contested 3. Sometimes, the guy will catch the ball and hit that big 3. But most of the time that's going to be a bad outcome.
I realize these percentages are extremely general, but let's say Channing Frye contributes very positively on the offensive end in 3 of every 10 games, and let's assume that the same is true about Diaw. Having two inconsistent guys subbing in and out for each other does not make it more likely that our power forward position will have a good game (either in the form of Frye, Doris, or a combination of the two). In fact, it's just the opposite. It means that we have two guys who have 70% odds that they're going to play poorly. You might say that the coaches will easily be able to see that one of the guys is playing a crap game and insert the other guy, hoping that this will be one of his good ones, but it doesn't work that way. With Frye, he's usually consistent within each game - if he starts out shooting poorly, he's probably going to continue to do so for at least the rest of the game, if not the rest of the week. With Diaw, he might string a couple of good sequences in a row, but he has a proven ability to go from hot to not (as in not noticeable until he reminds you he's in the game by doing something stupid at a crucial time) at any time. That's not the kind of guy you want on your team. Then, you add that to the fact that he's overweight!! Winners don't like to play with losers, but they're going to be much more willing to tolerate the costly mistakes of a loser if he's really demonstrating an effort not to do so. When 39 year-old Grant Hill just spent 40 minutes chasing Kobe Bryant around screens, pushing him off the block, taking charges, and then get to the offensive end and still have enough left in the tank to create scoring opportunities for himself and his teammates as often as anybody else on the team, and Grant Hill's team loses 108-101, the absolute LAST thing you want to see in the locker room after the game is the guy who can barely contain his excitement about the free tacos he's about to get because the Suns hit that all-important 99-point goal.
