Munson's right on the borderline as is, and given the tragic death while still playing in a big market, it's kind of surprising that the Veteran's Committee never put him in. If he doesn't die and plays 5 more years, he's in for sure.
But if Munson is in, Gene Tenace has to go in - remarkably similar resumes and there are stats where Tenace outpaces Munson (including rings). So I figure they don't want to open the floodgates by putting a borderline case like Munson in.
Mauer absolutely deserves it. The one that's going to be interesting is Posey. When he was on the field all you could think is that this guy is a future HOFer. But he retired young on his own terms. Has 3 rings, ROY, MVP, Gold Glove, and Silver Sluggers in his trophy case. But because he retired at 34 he doesn't have a lot of the accumulators or grand totals they look for.
