Even 7 foot guys like Rasheed Wallace and Kevin Garnett take 40% or more of their shots from 3 point territory. Wallace shoots 35% on three pointers (30% is the "he's a good three point shooter" threshold). The real three point shooters make half of their shots... a feat of accuracy which is really fucking hard, even more so considering they also have to get to the shot and deal with defense. There is no question most basketball players are genetic freaks but anyone playing in the NBA these days is also scarily accurate.
I hate to agree that I now find the NBA kinda boring... but it's not because it's a circus act (circuses are pretty interesting, actually.) The NBA is boring because almost every player is now so superhumanly good that it's hard to imagine how difficult what they are doing really is.
