Who is the greatest wrestler of the year?

It's quite comfortably Cena for me. A tremendous one-two series with Umaga at New Years Revolution and the Royal Rumble. A great match with HBK on Raw (most people consider the WM main to be a good but I find it to be his only black mark in that title reign), a great set of title matches against nearly everyone on the roster, most of whom weren't workhorses, such as Khali and Lashley. He had arguably the best match with Orton at Summerslam and had a solid rematch at Unforgiven. It's unfortunate that he got injured before they could compete the trilogy because I think that would've only bolstered his case. Cena truly became the best wrestler in 2007. 

 

Other candidates will probably be Umaga, Hiroshi Tanahashi, Yuji Nagata, etc. 

Bryan I think takes 2006-2009.

Danielson probably takes it but Nagata provides some stiff competition. The Makabe bloodbath (my MOTY), strong bouts vs. Tanahashi, Suzuki etc.

I'll go with Randy Orton as the dark-horse pick. Multiple great heel performances in a solid number of really good-great matches (e.g., NYR tag, Cena Summerslam, HBK Survivor Series etc.)

Danielson gets it easily, Nagata is my second.
