Nathan's career has not been short though. I've made this argument before, but I think Nathan will end up getting in after some Blylevenian wait and SABR debate. I think he'll get in due to his dominance during his peak years. Considering the innings pitched, closers generally don't produce a ton of WAR. I know, WAR sucks, blah blah, but considering how few variables there are for a closer, it actually matches up well for this position. A 2.0 WAR is a pretty good season for a closer. Joe Nathan just finished his 6th season with at least 2.8 WAR. Mariano Rivera is far and away the best closer ever, but as relievers, HOF'ers Rollie Fingers and Dennis Eckersley have a total of five 2.8 WAR years. Combined. Trevor Hoffman only had 3. Contemporary, and possible Hall stumbling block Billy Wagner had 3. Other contemporary top closers Jonathan Paplebon, Francisco Cordero, Francisco Rodriguez and Jose Valverde have six years with a 2.8 WAR. Combined. This of course this isn't an end all be all argument but I think it shows how much more dominant Nathan was than his contemporaries save Rivera. He'll likely still need to pitch well a couple more years to pad his stats, as HOF voters like traditional stats too, but he's in the top 10 in saves now, that's a Hall worthy argument in itself. I think 59 more saves to get to 400 would be hard to argue against and barring a complete nose dive in 2014, I think he's a shoe in to get there in 2015. 4th all time in saves is well within the realm of possibility which I think would put his odds very high.
