I don't think anybody is going to say that losing JR, Kurt and picks for nothing was a good move. I will defend Shaq for Marion and Banks though.
This was my point. I can understand why the salary dump moves last summer are still painful. Just like the using those picks to dump Googs back in 2004. (I'm still pissed about that one). Another was using a pick to unload Brian Grant - another messed up decision. We can rehash every bad pick and poor signing until now to doomsday and it won't help unless someone has a time machine.
The only issue I was concerned about is whether the Shaq for Marion deal made sense. All in all, I think it has worked better than keeping Marion would have. I always opposed the pure salary dump deals that people kept coming up with for Marion, but there was a risk that his tendency to be a locker room problem was making Shawn a liability.
As it is, I've always felt Shawn was not much help in the half court offense. He cannot make his own shot and is a weak three point shooter (career 34.1%). With the Heat, he shot only 25.8% for three (after shooting 31.7% for three in 2006-07). With the Heat he shot only 45.9% after averaging over 50% with Nash and the run and gun Suns
It's not that Marion didn't make a big contribution to the Suns success, but he was never as good in the playoffs. As it was, even his defense of Parker was only relative. Parker averaged 20.8 ppg on 45.1%, so it wasn't like Marion played shut down defense on Parker. He could not defend on the inside without a lot of help.
The sad part about this was that the best lineup from a defensive standpoint included KT at PF and Marion at SF. But with Marion being no serious threat in the half court offense and KT limited to jump shots; the Suns offense broke down while only slightly slowing down the Spurs.
The unusual aspect of last year's series was the Marion actually shot better against the Spurs than during the regular season. This was mostly because he was left wide open and he went through one of his infrequent hot streaks (8 of 17 for three). But in the first round he shot only 23.5%.
In the end, Marion was only marginally effective in the playoffs even when he was at the top of his game. With the Suns inability to beat the Western Conference teams, it was clear that Marion was no longer at the top of his game.
