The first major disappointment in a long string of the for Wolf was his 2009 O performance. I believe he disregarded the diet Chad wrote up for him, and spilled over. His color was awful as well.
He also was slightly off in 2008 compared to his breakout 2007 showing. Honestly, if his career is over at this point he didn't live up to the promise he showed early on.
Also notice that he still had calves at this point.
