Polley's 3rd most played lineup last year was Gilbert, Vital, Adams, Polley, Carlton and 4th most was Gilbert, Vital, Adams, Polley, Akok. He had a few possessions with the same 4 and Whaley, but not as many. Then there are a few other lineups with the same core group but Bouknight or Gaffney inserted or whatever.
The beginning of the year starting lineup (Gilbert, Vital, Polley, Akok, Carlton) accounts for 40% of his total possessions. However, of the all the remaining lineup combinations outside of garbage time, 45% of them had him as a stretch 4 (about 25% of his total court time). I would consider that a substantial amount of time, regardless of what Hurley said.
