i could see the case for having bradley on the playoff roster. in an ideal world, he would be used on the last possession of each of each quarter (except the 4th) to defend whoever the ballhandler is (billups, dwade, rose, etc.). other than that, id see no purpose for him.
altho i think wafer is better than sasha, against the knicks, id give the nod to sasha simply because he is bigger and has a better chance of guarding melo than wafer. against miami, i think we might need sasha and wafer simply because of potential foul trouble lebron and dwade could cause.
