BTW...
I am very consistent with my criteria for judgement. I may cherry pick at times, but my history shows I do not value recent season as much as others and I like to use the previous 3 year sample size and then lower the PAs to the point where the sample size is 30 players, since there are 30 teams. (At times, I will go back 4 years, if one season was greatly affected by an injury.)
Saying someone is 8th best out of 14 says very little, when there are 30 CF'ers in MLB. Is the 14th out of 14 CF'er the worst in MLB? I seriously doubt it. He was good enough to play more than at least 16 other CF'ers. A sample size of 1000 PAs is large enough to flesh things out and rank players by the true factor: 30.
Yes, JBJ is streaky. If someone wants to say he's only as good as 2017 or 2014, fine, but one could say that is cherry-picking, too. I guarantee no GM looks at just a player's recent 1 season sample size. Every GM would love to have JBJ on his roster, especially at his low cost.
I never said he was "great". I claimed he was close to top 3rd and had value. There's a huge difference.
Change the sample size to 2014-2017 and all that "qualify. JBJ ranks...
20th out of 42 in CF OPS (.732)
4th out of 13 in UZR/150 (+9.8) and 39 DRS (9th out 38, if you go by 1500+ innings)
So, basically, he's an average hitting CF'er and a top 3rd defender at a very key position in baseball. To say that has little or no value is illogical.
