Birdman is shooting an INSANE 86% from the field , on 43 shots. Thats like Ray Allen FREE THROW %. Only adds up to about 3 FG attempts a game, but still. And for the advanced stats guys, 28.3 PER. Can't consider that just all hollow production. Still, it isnt that hard to replace some of his 15 minutes per game. If their other star players play like they're supposed, it can offset Birdman's absense. And Haslem is also shooting incredible from the field so there probably is some lack of gamplanning on those other frontcourt players outside of Bosh.
Their defensive strat has been to key in on driving lanes and prevent Lebron and Wade breaking down the defense, and in the event that they do, the help man is in position to cut their lane. Andersen has received a lot of good looks, but he's also been great at cutting and being in position and, obviously, finishing the play.
Comparatively Bosh is playing like a stretch-4 or stretch-5, his position on offense has been further out from the basket waiting for kick-outs.
