Fighter of the year? Brock Lesnar, he has injected new life into the HW division and started his career taking some VERY tough fights and succeeding beyond what most people have expected. He's wearing the belt in less than a year, all accomplished in this year.
UFC Fight card of the year? UFC 92, Forrest/Rashad for the LHW belt, Nog/Mir for the HW belt, Wandy/Rampage III, what more could you possibly ask for in a PPV?
Fight of the year? Chuck/Wandy, it was a LONG time coming and they didn't disappoint in the least.
Worst fighter of the year? Kaleb Starnes, do I really need to explain?
Worst fight of the year? Marquardt/Leites, a barnburner that got totally ruined by fouls and deductions and left more questions than it answered.
Worst fight of the year was a tough one, there were many candidates but ultimately I sided with the fight that I thought had the most unintuitive result based on the action in the octagon. Alves/Hughes was a close second, Hughes agrees to fight an overweight Alves and earns himself a severe knee injury for his trouble. Sad. I didn't bother listing the Starnes fight because I thought it went without saying, that's just a given for the top spot. Let's not pick the low hanging fruit...
