Why the lack of love for the Crime Dog? Put his #'s next to those of most any that list and he smokes them and he did play defense (at a high level) and was never linked to 'roids. The man even stole 75 bases, not too shabby for a 1st bagger. I nearly added Dave Parker too but I had to cut off somewhere and I couldn't quite justify it.
On Martinez and Baines my position is you'd better have some specific milestone #'s or a smidge better (because their career was extended by the position) than most to get in and I just don't feel they qualify.
On McGwire, I believe he used roids and I think if it's illegal then it's in the rules even if it's not spelled out for them specifically IMO. Therefore you cheat you don't make it, sadly same goes for others of that ilk.
