Eh...starting Green messes with the bench's chemistry they've created over the last five/six weeks, and right now they are the only reason we are competitive most games. I'd only put Green in the starting five if he was taking Pierce's spot and Sullinger replaced Bass. It's not the biggest sample size, but our most productive units this season all include some combination of KG/Green/Sullinger with Rondo or Terry running the point:
Garnett | Green | Sullinger | Lee | Terry/Rondo 122min +40.4
Garnett | Green | Sullinger 243min +19.0
Of course, these units are most likely facing the opponents bench, so the numbers don't tell the whole story, but it's clear that they work well together. A line up of KG/Sully/Green/Bradley/Rondo could be effective...the 2nd unit would be worse off though, and I'm not sure benching your best scorer is the smartest idea.
But something clearly has to be done, because whatever they're doing now isn't working, particularly with the starters. It's crazy to compare their production from last season to now; what a difference a year makes...
2011-12: Bass | Bradley | Garnett | Pierce | Rondo 218min +19.4
2012-13: Bass | Bradley | Garnett | Pierce | Rondo 111min -6.5
