Well...since Dan is of "suspect moral character" and all that I guess we need to find a Crossfit endorsed coach for a definitive answer. Unless the roster has changed Coach Mike Burgner is the CrossFit O-lifting coach...and HE teaches the snatch first.
Now obviously there are loads of ways to approach this but between these two guys we have...what like 200years of coaching experience (just kidding guys, don't kick my ass!).
I don't know...who better to listen to than two coaches who teach these movements for a living? I'll do some digging but I think John Davies (Renegade Training) teaches the snatch first. Pretty compelling to me.
