As far as fielding counting if anybody says Brooks Robinson shouldn't be in the HOF that's fighting words. He's the best fielding third baseman I've ever seen. Which brings up Manny Machado. If he plays many years at third he might qualify for the HOF even if he finishes with pedestrian numbers.
Which is rather amusing considering that Machado's career averages so far (using your metrics) are .282, 25 HR, 73 RBI. Basically Ripken, in other words. So if Machado plays 3B brilliantly, he's a possible HoFer and if he plays SS decently he's...well, what?
