Of the 10 players with the most similar ranking to him only Robin Yount, Charlie Gehringer(played in the 20's) and Joe Morgan have a higher WAR. Morgan, Chuck G, and Molitor ahead of him in OPS+. Morgan and Chucky G in OBP. Those last three will be dragged down by his longevity too. He was an elite player for a longtime. Sure his fielding is wildly overrated by some people, but he is absolutely a Hall of Famer without any doubt. The only people that would leave him off are shitheels trying to send some stupid message or get publicity, the same type that kept guys like Nolan Ryan or Willie Mays from being unanimous. Some players are no brainers, a HoF vote isn't meant to be something for the voter to leverage for their own notoriety or retarded agenda.
He was also integral to 5 World Series winners. And if anything played better in the postseason.
And make no mistake, not voting for someone purely because "no one should get in 1st ballot" is flat out fucking retarded.
