Trout has passed negro Bob Gibson on the all time WAR list:
What speaks to the greatness and what could've been is the number of plate appearances Trout has compared to HOF's around him. (Not counting the pitchers as WAR is figured differently for them. Notice George Brett's number of PA. 11,625 to get to 88.7 WAR. Trout has only 7437 to reach 89.6 WAR. Carl Yaztrzemmski needed almost twice as many PA's, to reach 96.5 WAR! 13,992.
Pete Rose needed 15,890 to reach 79.6 WAR!
Being relatively conservative, I would say if Trout had not missed the equivalent of 3.5 seasons, he would've mostly likely already passed the likes of number 21. Mickey Mantle, 110 WAR, 19. Rickey Henderson, 111.2, and 18. Lou Gehrig, 113.7 with 4- 5 seasons left to catch Williams, Musial, and maybe Cobb.
Unfortunately, we'll never know. Still for me, Trout is the greatest MLB player I've ever seen...or at, least for 6-8 year span.
