Last weekend they beat the Bucks in Milwauke without KG, and down the stretch used TA and went small. After the game Doc said the only time he doesnt mind matching the other team and going small is when they dont have KG, because he doesnt feel Baby or Sheed have the footspeed to defend quicker 4's.
Id consider Beasley a very quick 4, so while i think they start with Baby or Sheed, you will see a fair share of small ball. Something like Rondo/TA/Ray/PP/Perk, that way you have TA on Wade which saves Ray energy, and you make and Q-Rich and Beasley have to chase around Ray and Pierce which will wear them down. Plus, i dont think Pierce would have much trouble defending Beasley, who is only 6'7 or maybe 6'8.
