just made me laugh out loud. i definitely would pick tmac or baron's dunk. prolly would go with TMac cuz I'm a fan of his (although I haven't gotten to root for him recently...) and that dunk was pretty nasty.
note: if you look at the youtube version of TMac's dunk that was posted in the OP, i found it pretty funny that one of the Rockets rolled over on the sidelines right after the dunk lol
