I'm too lazy to look up the rest
Huge difference between the best catcher in the game and the best hitting prospect of ALL-TIME. Also, there really aren't too many guys catching in the majors right now that excel at both offense and defense so the fact that Wieters has very good potential in both areas could lead someone to make that speculation. I would certainly not begrudge anyone the argument that Buster Posey (who plays very good offense and defense) could already be the best catcher in baseball right now (though I would still say Mauer). But he is nowhere close to establishing himself as the best of all-time yet.
