I. There is no evidence that Shaq has helped the Cavs this year.
A. Cavs record last year: 66-16, Avg. Margin of Victory 8.93
B. Cavs record this year in games w/o Shaq*: 18-2 (10 Home, 10 Away)
(Opponents winning Percentages: .397), Avg Margin of Victory: 8.35
C. Cavs record when Shaq plays: 40-13, Avg Margin of Victory: 7.28
D. Shaq's plus/minus data: -3.13
* I disregarded the two games that are played w/o Lebron
Now, in fairness to Shaq the schedule has been soft w/o him in the lineup and it was hard with him. But overall body of evidence supports the conclusion Shaq hasn't helped the team. They were a better team last year. They have a much better record when he is injured. They have a larger point differential without him. In games when he is not injured the team plays better with him on the bench.
II. The Suns have been a much better team this season than last season.
A. 2009 Suns Record: 46-36
B. 2009 Suns Point Differential: 1.93
C. 2010 Suns Record: 49-26
D. 2010 Suns Point Differential: 4.59
The Suns have been markedly better this year after basically giving Shaq away. Originally, tsherkin felt the Suns would skid out over a hot start:
viewtopic.php?f=64&t=980729&p=22091976#p22092947Steve Nash is playing better, and the Suns are skidding out HARDCORE this year. They won 46 games last year and while it's true that they're on-pace for about 45 this year... they started 14-3 and have since gone 8-18.
Now, that argument is no longer valid so tsherkin offers several different reasons for the difference in performance which I will address later.
III. Shaq's hurt the 08 Suns
Shaq, was acquired in a mid-season trade with Miami. Shaq missed the first few games and played his first games against the Lakers.
A. Phoenix Suns before making the trade. 34-14,
Avg Margin of Victory: 6.14,
22 Home, 26 Away
Opponents winning percentages: .465
B. Phoenix Suns w/Shaq in lineup: 17-11
Avg. Margin of Victory: 3.32
15 Home, 13 Away
Opponents winning percentages: .563
Now, the schedule was harder with Shaq, but the drop off is quite large. The Suns were playing like a title contender before making the trade, and weren't after acquiring him.
IV. Summary
Shaq for the last three seasons have been tied to teams that achieved better results with him elsewhere. I have established this through several different measurements. Thus, I have presented sufficient evidence to support my position that Shaq hasn't helped team. tsherkin offers several counter-explanations that I'll address.
V. The Suns success this year and failure last year is difficult to tie to Amare..
Amare, despite his box score numbers has not been essential to the Suns success this year. He has a terrible plus/minus -6.13 (http://basketballvalue.com/teamplayers. ... 0&team=PHX). The Suns have generally played pretty well in games when he was injured outside 2009. That's why I'm quite skeptical of the idea that Amare's injury caused the decline of the Suns.
VI. The coaching change didn't really help the Suns that much.
A. Under Coach Porter: 28-23, ( 24 Home, 27 Away) (Avg. Margin of Victory: .941)
B. Under Coach Gentry: 17-11, (17 Home, 14 Away) (Avg. Margin of Victory: 3.921)
Now, as you stated we only had a two game body of evidence to see what the trio of Shaq, Amare, and Nash could do together, but based on the three seasons worth of evidence we have, I see little reason to think they would be doing better with Shaq.
btw: Shaq did steal Nash's idea for a TV show so he wasn't totally drama free.
VII. Conclusion
Shaq's arrival in Phoenix marked the immediate end of the Suns contending for championships. Contrary to myth they were still playing like a title contender before the trade. Shaq gets traded away from Phoenix for basically nothing and the suns immediately improve. The cavaliers have played slightly worse this year in comparison to last year, and play better with him on the bench in games in which he isn't injured. I don't believe he helps teams anymore despite the nice box score numbers he still puts up. I'm curious for others thoughts on the matter.
