This what gets me the most. I kept thinking I saw some improvement, and then the next year he stayed the same or even got worse. He's been yo-yoing. I don't look at UZR/150 until at least half way through a season, unless I'm looking at 2-3 year samples for a discussion. I like to go by what I observe and then look at the numbers to see, if they back up my thoughts. They usually do.
Here's how I have viewed his progression:
I gave him a pass year 1 & 2, as they jerked him around a little by using him at 3B and then re-signing Drew.
He did better year 3 (2015), and I had hopes he'd keep improving. He was plus 2.9 on UZR/150 and just -1 on DRS.
He looked worse in 2016, and quite frankly, that pissed me off. I even suggested (again) we move him to 3B. He seemed to improve a little in 2017, but I didn't think he played as well as 2015- better but not his best.
He's looked better this year, so it's nice to see 2 years in a row of getting better, but I still only put him slightly better than he looked in 2015, so it's hard to say he's at his best or "peaked" or about to "peak."
I'm glad he's gotten better, although the DRS numbers have him at his all time worst (-17) this year).
I'm happy with Bogey as our SS. He's hitting great, his defense seems better, and we don't have anybody else, really.
