I'm not saying whether he belongs or not, but I looked up some career rankings on Fangraphs and Baseball-Reference, and here's what I've found: Case for him: He's 10th all-time in fWAR among catchers. As Derwood pointed out, that is LARGELY due to his defense. According to Fangraphs, he's tops in Defensive Runs above Average (380.4) all-time among catchers...with a fairly significant advantage over I-Rod, who is second at 320. So it's not just that he's really good defensively, he's arguably the best ever at that position. Baseball-Reference paints a slightly different picture, giving I-Rod 29.6 DWAR and Molina 26.3. However you slice it, he's still one of the best defensively ever at that position. Case against him: If you look at the top 60 catchers by fWAR (possibly more, since I didn't go to page 3 of that list), Molina has the second worst Offensive Runs above Average (-106.3) of the entire group. The only one in that group that is worse is Bob Boone (-186.8), and he clocks in at 38th all-time in fWAR among catchers. For context, Russell Martin is 11th all-time in fWAR among catchers at 55.2, and he's at 13.6 Offensive Runs above Average, while Brian McCann is 12th in fWAR at 54.2 with 24.3 Offensive Runs above Average. For even more context, a lot of people say that Ozzie Smith did not have the offensive profile of a Hall of Famer. Like Molina, Smith is tops all-time at his position in Defensive Runs above Average (and he's tops among ALL players in DWAR at 44.2 according to Baseball Reference). However, Smith was at -69.4 Offensive Runs above Average, markedly better than Molina. I think Molina is getting in, and it will have nothing to do with stats. He has been over rated by the baseball pundits for 18 yrs. It will be something along the lines of "Molina brings an aspect to the game that cannot be measured."
