I do have to mention, since it popped in my head. My dad and I one time a long time ago were discussing all-time teams. He being the Yankee expert (fan since a kid listening to the end of career DiMaggio on radio). And he did mention an interesting suggestion. That as loaded as the Yankee lineup would be. Mantle might be the perfect leadoff hitter for such a lineup giving his skill. He had speed, smart baserunner, and could draw oodles of BBs (course that BB drawing isnt exactly unique in this loaded lineup). This was before Brady Anderson's 50 HR season mostly at leadoff, too. Course, this was when Jeter was a rookie if I remember. So, the lineup would be different.
Note: As a sidenote, when talking about the Yank all-time SS. He said "probably Rizzuto now, but ask me again in 10 years".
As far as Fisk is concerned, I was trying to think who would be the C for his teams if he didnt exist. Probably Varitek for the Red Sox. And for the White Sox, Ray Schalk is the best I can think right now.
