The Celts primary disadvantage against LA is LAs length and matchup problems. The Celts are holding LA to 95.7 ppg which is good enough to win. Celts need to up their offense, neutralize LAs length and create a matchup advantage of their own. To do that they need to start Wallace in place of Perkins which does all 3. Here's why:
1) Perkins provides no offensive threat. Wallace is a good scorer.
2) Perkins and Bynum clog the middle not allowing Rondo or Pierce to get in the lane where they are both extremely effective. Wallace stays at the 3 pt line and draws LAs length far from the hoop where it is ineffective. And it creates a matchup problem as Bynum and his gimpy knee will have a tough time staying with Wallace or Garnett. Bynum was last seen on the bench nursing a tweaked knee. Imagine Wallace at the 3 line and Garnett 18' out. That leaves the lane wide open for Rondo to drive and create and Pierce to finally be effective on offense by driving and getting fouled. The offense improves dramatically as all 5 Celts would be offensive threats whereas now it is only Allen and Garnett, and that is only when their shot is on, which has only been one game for each so far. This gets Pierce in rhythm (essential), and the Celts are at their best when Rondo can drive and create. And it would be easier to create with an open lane and 4 offensive options to pass to. Pierce and Rondo are more dangerous on offense with Wallace in, and Wallace is always more of an offensive threat than Perkins.
3) On defense, Wallace is at least as good as Perkins. He has demonstrated that in guarding Howard and Gasol. For example, Perkins has no blocked shots and Wallace has 2 blocked shots in about half the minutes. Wallace would guard Bynum rather than Gasol if needed which would help stay out of foul trouble.
4) Rebounding - Wallace is leading the team in rebounds/min against LA
5) Wallace's best value in this series is when both Gasol and Bynum are in because Wallace can best neutralize LAs length. Hence, play Wallace at the start when both of LAs big guys are in.
6) Pierce needs to get going from the start, and its not likely to happen unless he can drive, which he can't with a clogged lane. Wallace needs to play when Pierce and Rondo are playing which is the start of the game. Pierce is only shooting .361 in the current system which, predictedly, isn't working.
7) This new dynamic offense would help get the crowd into the game.
Provides an element of surprise for the essential game 4. LA would be forced to adjust.
9) LAs length and matchup advantages are clear. Boston needs to do something significant to change that dynamic.
10) Boston is getting killed in the first 3 quarters by a total of 26 points and winning big in the 4th quarter by 15. Even in the 2008 series LA generally got ahead early. Boston needs to get off to a better start and set the tone. The team that has been ahead after one qtr has won each game.
11) Guarding Wallace or Garnett would help wear out Bynum's gimpy knee. Currently all Perkins does on offense is set screens. Bynum simply hangs out in the paint.
12) What do they have to lose? The current system isn't working even while Kobe is off, which won't last forever. The Celtics will need more offense.
In case you haven't noticed, Wallace leads all Celts at .27 bounds per minute and .600 bounds plus points per minute, shooting a solid 5-6 from 2 pt range and 2-8 from 3.
It's not too late to make this bold move, but it may be after Thursday.
