In his defense, here's a rundown of what I feel is his good-or-better output, post 2001 -
2002 - v Angle early in the year, v Jericho in HiaC
2003 - nothing
2004 - WM, Backlash, v Benoit at Vengeance, a great triple threat with Edge and Benoit in Nov/Dec
2005 - Elimination Chamber, HiaC with Batista, Flair in the cage match, a couple of good Raw matches with Benoit
2006 - WM (Bit torn here - not really a match that helped Cena, but he wrestled well), V Edge v Cena (Backlash). Not a fan of the DX stuff, but as the year closed they had a decent 6 man with Cena v Orton Edge Umaga
2007 - DX v Edge Orton was going very well until his knee fell apart, loved his streetfight with Umaga in October or November, and the LMS v Orton around the same time.
2008 - Really contributed to a very good Elimation chamber in Feb, good match v Edge in July, generally liked his move to Smackdown (Nice match v taker there) Really strong triple threat with Edge and Jeff Hardy in Dec
2009 - Good performance in Elimination chamber, and the 6 man tag at Backlash. Another DX reunion gave us one good match v Rhodes and DiBiase jr at Summerslam, and the ladder match v Jerishow in Dec.
2010 - liked the WM and Backlash matches with Sheamus
2011 - big fan of v Undertaker. Not so much the Punk and Nash matches
2012 - big fan of v Undertaker. Enjoyed the SummerSlam Lesnar match, but it looks very tame now.
2013 - Didnt like the Lesnar matches
2014 - Really enjoyed the WM match, and the first 6 man with Shield
2015 - Nope
