Ted Williams got my vote. He missed all of 43, 44, and 45. If you average the bookmark years, 42 and 46, then he should have had 3 seasons of .349/.498/.658 with a 216 OPS+ and averaging 37 HR and 130 RBI. Likewise, if he would have had a full 1952 and 1953, he should have been averaging .332/.489/.596 with a 183 OPS+ for those two seasons.
