I think using the small sample size argument he used for Nolasco and Hughes etc (bad signings, or extension, based on short sample size) is a bigger problem when you have a much larger body of work telling you that the positive short sample size you are using to make a call is clearly wrong. If Sano had been considered a superior fielding 3B in the minors and was having these issues, one might say, 'Okay, clearly rusty, or clearly not really bad based on all we've seen in the minors on defense.' Correct me if I'm wrong, but great fielder wasn't exactly Sano's scouting report in the minors. It's my understanding he's been suspect all along, no?
