I agree that last night's game was horribly officiated, and am really happy that KG said what he said after the game.
Having said that, I think part of the season wide FT differential is due in part to the Celtics either settling for jumpers, or not operating in the post. Take last night for example: After Rasheed went 5 for 5, and once he FINALLY got the ball again, he made a move that the Thunder had to foul on. Had the Celtics kept running some post plays they would have gotten to the line more often. Our player who is best at getting to the FT line, Paul Pierce, has been injured on and off and is now finally attacking the hoop. Other than that, KG is mostly a jump shooter, Ray Allen rarely attacks the hoop, Rondo rarely gets fouled around the hoop, and Perkins is lucky he doesn't get called for traveling. I guess what I'm saying is that you can't put much conspiracy stock in the Celtics season-wide FT numbers.
