I think its a great idea to start green at sf for many reasons, none of them are because he is a better player than pierce.
Green at 6'9" shows good low post moves, best guy we have on the block not named shaq. This changes our offense (especially if jermaine or krstic is center). Green will run, guy is young and fast, rondo will find him. He can defend the sf posistion really well and give pierce needed rest. Pierce turns into manu east, still playing starter minutes but not grinding it out for a whole game. Paul can create his own offense and anchor the entire 2nd unit. The move has NOTHING to do with green being better but it improves the team a lot. Green's productivity would go up and Pauls would stay the same. I'd still want paul ending games but could see an athletic lineup to finish, rondo, ray, green, pierce and kg.
no to green as starting pf,can't see kg keeping it together to come off the bench, he might chew on ed lecerte's leg!
