I don't think that stat says he has bad range, he had by far the most out of zone plays. It just says the doesn't play his zone well, and I've listed reasons why that could be, which extra out of zone outs agrees with. However, I've looked into it a bit, and Chris Dial's RSpt has Hudson at -4 compared to average, so maybe he isn't what my perception thought he was. Loretta was -7, so he's, what, 6 for 6 now with systems putting him well below average? Kinda tough to pick the guy that is firmly in the underperforming crowd in every system.
Yeah, because noboby ever improves after adjusting to a new level and their first 80 ABs locks them into a performance range.
