Millsap, Brand and Jamison no way. DeMarcus Cousins is a C. Josh Smith is playing SF. Troy Murphy, absolutely no way. Good player, good rebounder, no where near as complete as Blatche. I'm not taking Rashard Lewis either. Lewis is a good player but him playing PF is more out of need than skill. His best days were at SF.
You are seriously underrating Blatche. He had a bad game where he consistently faced double teams with no options to kick out too. He's a highly skilled forward who needs spacing on the floor to operate. Dwight Howard clowns a lot of big men in this league. Blatche had exactly the game I'd expect him to have going against the DPOY with very little perimeter play help.
