My favorite is a Simple Tomahawk jam where the guy just takes it up strong, puts it behind is head, and then just goes BAM on the rim. And i hate how every major site uses REal one, cant they just use WMP?
I've seen some nice two-handed, behind-the-head tomahawks this season... T-Mac did one on Christmas, and Kedrick Brown had a pretty good one shortly after being traded to Cleveland.
I think the best type of two-handed dunk is the reverse. Ricky Davis does a lot of those. LeBron had a huge two-handed reverse against Portland. If you count alley-oops, he also had an insane reverse alley-oop jam with two hands that he caught at about waist level. Against Washington I think.
Steve Francis does that great reverse that he pumps down between his legs... that's amazing.
