6 active MLB stars who are potential Hall of Famers, but still have some doubters
Predicting the voting and the induction process for the Baseball Hall of Fame isn't an exact science. There is an exact science, technically, in helping us to determine whether or not a certain player should get in: statistics and analytics. But all the statistics and analytics in the world can't help us to decide whether or not a player like Barry Bonds deserves to get in on grounds of fairness, or if Scott Rolen deserves to get in on grounds of consistency and offense-defense balance, or if Curt Schilling deserves to get in on grounds of morality and ethics.
And that's what makes speculating and debating about the Hall of Fame candidacy of various MLB stars so much fun. For some players, there's no speculation needed. I can think of seven active players for which this is the case: Mike Trout, Albert Pujols, Miguel Cabrera, Justin Verlander and Clayton Kershaw are five easy ones, and Zack Greinke and Max Scherzer fit the bill after a few seconds of deliberation.. They're no-doubters, shoo-ins, home-run candidates for the Hall, if you will.
According to the Jaffe WAR Score system (JAWS), Trout slots in right between Mickey Mantle and Ken Griffey in terms of his Hall of Fame likelihood among center fielders, and he's still got plenty of time left to go. Pujols ranks second among first basemen, trailing only Lou Gehrig, while Miggy ranks above names like Willie McCovey and non-Hall of Famer Rafael Palmeiro, whose steroid usage derailed his chances despite statistics that were more than enough to get him in.
Verlander's JAWS (60.9) ranks just below the average Hall of Fame starter's (61.6), though his achievement of 3,000 career strikeouts historically means he's in — Roger Clemens or Curt Schilling are exceptions to that rule for obvious reasons. Kershaw and Greinke have similar JAWS figures, well above several Hall of Famers, and both have room to grow. Kershaw has won an MVP award, a World Series ring, a pitching triple crown, three Cy Young awards and is only entering his age-33 season. Greinke still seems to have some juice left in that arm of his and could easily get to 3,000 strikeouts. The same goes for Scherzer, who is lower down on the JAWS list but has peak dominance that has rarely been matched, and he should have enough hardware on his side even if his counting numbers are a little low.
Outside of those seven names, I don't see anyone still playing as an absolute lock. The list of players below are ones who I think have a legitimate argument however, seeing as they are at or near a number of required achievements and are close to the end of their playing days. Who I'm not going to include are stars like Mookie Betts, Bryce Harper and Jacob deGrom, seeing as they may be on a Hall of Fame trajectory, but it's too hard to say that they are undoubtedly set for Cooperstown in the unlikely event that their careers suddenly hit a wall.
Now, the six names below are players who probably won't add much more, if any, to their career stat lines and could stir up some debate when they eventually find themselves on the BBWAA ballot down the road. But which of them will get in? Could it be all? Could it be none? That's the fun of it.
