The decision about Brad is the key because:
1) Brad Miller is necessary if we are going to run any semblance of our old high post passing big man offense
2) Mike Bibby's game would in particular be effected by Brad's loss, as he is a pick and roll two man game PG.
3) Peja is dependant on other player's passing as well, and the loss of one passer wouold likely hurt him a bit too
3) Therefore trading Brad has two major downsides: a) the offense goes with him; b) we lose significant production from one major returning player, and probably at least some from abother;
Now on the flipside obviously, Brad is vertically challenged, slow, and just got his *** handed to him all year by every opposing offensive player over 6'5" this season. On BOTH ends of the court mind you because he also is 7'0" with so little postgame that OGs can, and literally do, defend him with his back to the basket and embarrass him with their abiltiy to stop them inside.
Mike is a more independent decision -- if Brad goes, Mike's value to us drops. But if Mike goes first? Well if he is not replaced with a serious replacement EVERYONE's game sinks a bit as we lose our PG and court leader, but if he's replaced by a quality replacement there is no one player who's game is especially apt to suffer (the closest might be Mo Evans who early in the year seemed to really be ont eh same page with Mike for flying alley oops).
Peja is more independent still, sorry funkykingston, but I DO agree in general with the "parasitic" comment. He takes, but does not give back. He needs help, but does not help in turn. And that "selfishly" (for lack of a better term) oriented game carries over onto defense -- he is solid on his man, but his help defense sucks and he's never been willing to so much as break a nail on the team's behalf on the hustle board. Its all about Peja. Peja's shots principally. You guys take care of the boards, the hustle, the passing, helping others, including me at times, on defense, oh, and by the way, would you mind terribly setting a whole line of staggered screens for me so I can get off an open jumper which I can't create for myself? If we had a great post player Peja's presence on the perimeter would create some space (although I have mentioned before that perimeter guys are rarely doubled and its hard to do so, so an outside guy does not create nearly the defensive distortion a major post player does) -- but as it is, EVERY single player in the Kings starting lineup at season's end was a jumpshooter first and foremost. Jumpshooters create minimal space for each other. And with SO many jumpshooters, Peja's individual impact on our spacing is minimal -- EVERYBODY is outside, everybody creating the same type of space as Peja does. Bottomline? If Peja leaves there is not a single player on the team obviously damaged by his departure. Not one. Nobody who he sets up. Nobody who he creates for. Nobody who his game is designed to help. The TEAM could still lose ground if we did not get back the right player, but Peja's game doesn't particularly help anybody but himself.
I'm not the least worried about a spillover effect from trading Peja. I'm considerably worried about a spillover effect from trading Bibby, but it all depends on what we got back. And the Brad decision is tough, his defense is truly problematic inside, but he's a fairly unique player in his suitability to run our offense and the obvious effect he would have on at least one major King's game. He, at least, you might keep around not because of his individual brilliance or overall talent, but because of the effect he might have on everybody else if he's gone.
