I was a huge JBJ fan and supporter, when people bashed him. I loved his defense. He made hard plays look easy, and maybe that hurt his image, a little.
At his peak, I'd have no issues saying he was as good or better than Kike, and it might not seem fair to penalize him for longevity and decline, but that's my own personal perspective.
Lyn was unbelievable. That 1975 season was fantastic- both on O and D. He was great on defense for a few years with the Sox. He went all out and got hurt playing 110% all the time. Again, with him, I'd have no beef with anyone calling him the best.
I just think what I saw of Kike, this year, we the best I have ever seen in a Sox CF'er. The metrics don't back me up, but it's what I think, right now.
