Gary Russell Jr. went to the olympics, but failed to make weight. Seth Mitchell got into boxing too late to make the 2008 games, so wouldn't be worth him waiting for 2012. A lot of good boxers from the USA you assume chose to turn pro instead of going to the olympics actually tried unsuccessfully to make it to the olympics. For example Timothy Bradley, Lamont Peterson and devon alexander turned pro after unsuccessful olympic team trials or qualifying tournaments.
high scoring bout! no surprise cuban wins. . . best ammy boxers in the world. i didn't expect diaz to make it past this round. i think spence, and the lightweight dude are the best chances for medals.
