When the Heat go big and play Wade/Lebron on Rondo, the c's should go bigger putting Steamer in with KG. With KG and Steamer in there you go to the zone and pretty much guarantee the Heat will become a jump shooting team in the half court.
Like Dennis Scott just said on NBATV, The reason the zone worked for Dallas last year was because that had a 7 ft shot blocker controlling the low post. This is Steamer's biggest strength and by playing zone it lets him stay away from his biggest defensive weakness which is guarding the pick and roll . This also lets KG roam and be the great help defender he is .
The heat won't be able to get away with playing Wade and Lebron at PG if we go big with Steamer and KG because Battier won't be able to guard KG in the low post and the c's would have a rebounding advantage with two 7 fter's (at least I think

)
anyways, just a thought ....
