I saw a brief discussion on ESPN about Dunn from Reynolds and Plesac last night. They mentioned that Dunn went from the terrible 2011 to the "improved" 2012. They even laughed that last year was considered a great improvement since 2011 was so bad. But they wonder if the poor start this year will be a huge mental block for him since he is in 2011 mode only worse so far.
Speaking of sabremetrics----how about the NFL Draft. They live and die by sprint speeds, arm lengths, lifts etc. Everbody seems to be pigeon-holed by statistics.
