Unfortunately the data differs with you. Oh, and so does watching the games.
These following lineups all outscored the opposition when they were on the court last regular season:
Williams-Matthews-Miles-Millsap-Fesenko
Williams-Matthews-Miles-Boozer-Okur [Notice that PM and KF do just fine without 'em]
Williams-Miles-Kirilenko-Millsap-Fesenko
Williams-Matthews-Korver-Millsap-Fesenko (Swap in Hayward for Korver as an equivalent)
This one was one of the worst, yet it was one that was used among the most:
Williams-Matthews-Kirilenko-Boozer-Okur
