Tendencies aren't worth much. With such a small sample size and so many other mitigating factors contributing to each pick, it's hard to clean any relevant data from even a ten-year draft history. Short of actual quotes along the lines of "I don't draft goalies in the first round" or "I won't draft Russian players after the second round," I wouldn't put much stock in them, and even then, you have to be wary of smokescreens and gamesmanship.
As far as which league to draft from, it's a player-by-player case, but the Wheeler and Turris cases are both unique. With Wheeler, he exploited a loophole with which we're all now very familiar. Turris was just rushed. Had he spent an extra year or two at Wisconsin, he could have been much readier for bigger minutes, and he never would have had his little fit in the first place. That said, there aren't a ton of NCAA-bound guys projected for the first round and certainly none in the Coyotes' range, so this may be a moot point barring a big trade down.
