I like Matt Olson, but Hall of Famers generally feel like Hall of Famers. Olson doesn't give me that impression right now. He reads as consistently very good rather than truly elite. Maybe that changes if he sustains this level for another 6+ years, but at the moment his peak just doesn't stack up with players who either don't get in or get criticized for getting in.
Take Andruw Jones, for example. Yes, comparing a center fielder to a first baseman is kinda dumb, but Jones is someone many people argue against as a Hall of Famer , yet his peak is still on another level. Jones posted bWAR seasons of 8.2, 7.4, 7.1, 6.7, 6.5, and 5.6. That's six seasons of legitimate superstar or MVP caliber production. Olson, by comparison, has seasons of 7.5, 6.2, 5.9, and 5.1. Fewer elite years, and the top end isn't as high. Unless he's about to have a late career surge like Bonds, Beltrn, Beltre, or Ortiz, I don't see Olson getting close to Jones's peak value.
I think position is also important to consider. Look at the last several 1B to make the HOF.
- Frank Thomas - 154 wRC+ / 72.1 fWAR
- Jeff Bagwell - 149 / 80.2
- Jim Thome - 145 / 69.0
- Fred McGriff - 134 / 56.9
- Matt Olson - 134 / 35.0
- Todd Helton - 132 / 54.9
I'm not sure he's got another 20 WAR left in the tank, not to mention his offense is already near the bottom of the HOF threshold before late-career decline.
While I think the modern ironman is cool, he's probably not quite good enough.
