Let's not act like all of these are completely ridiculous or unexpected.
-Koji had a 2.36 ERA from 2010 - 2012, he was (somehow) completely underrated.
-Victorino had the exact same WAR in 2011. He was literally 1-year removed from that exact same WAR. It wasn't his career best. He played as well as he did, LITERALLY, 2 years prior to that.
-Napoli had the 2nd highest WAR of his career because he played 1B, not C, where he played more games. Believe it or not, Games Played are a major contributing factor in WAR.
-Ortiz had (nearly) the same WAR as 2011 (3.9 to 3.8). And guess what? His 2012 WAR was 2.9 over 90 games. Over the same 137 games he played in 2013, that would be a 4.4 WAR. So, this is again a garbage statement.
-Pedroia's UCL affected his SLG. His WAR is always impacted strongly by his defense, and he has always always been the best defensive 2B in the MLB, that didn't change, that's not playing above his head. That's not overachieving.
-Buchholz posted a 3.2 WAR. He pitched 108.1 IP. To say that he "overachieved" when he was hurt for literally 1/2 of a season is grasping at straws.
-Lackey had TJS, and he's a better year this year than he had last year, based on FIP and xFIP.
Drew and Nava played well above their heads. But the rest? That's you grasping at straws man. Thats you bitterly grasping at straws, trying to manipulate statistics (i.e. referencing WAR without referencing games played as the main deterrent), and laying out complete BS.
