Every other day for the next couple of weeks InsideThunder.com writers Randy Renner and Jeremy Griffin are taking an in-depth look at the Thunder roster and discussing which players will be back for next season and which ones probably won't be.
On Monday in Part 1 they looked at Thunder head coach Scott Brooks and two of the Thunder's Big Three, Kevin Durant and Serge Ibaka.
Wednesday in Part 2, they examined the changes that could be on the way for some key bench guys, Reggie Jackson, Caron Butler and Nick Collison.
Today the focus is on three players who've been mainstays in the starting lineup, Russell Westbrook, Kendrick Perkins and Thabo Sefolosha. Is at least a partial breakup in the cards for these three??
