Been wanting to do this for weeks and we got like five days left but here are some WWE tv matches I remember thinking were - and/or still think are - good. Even if not necessarily top top notch, still good and worth noting, for a lot of them have gone under the radar over the years, similarly to the aforementioned Masters vs. McIntyre.
Christian/Kane vs. William Regal/Ezekiel Jackson (ECW 1/26/10)
Rey Mysterio vs. CM Punk (Smackdown 2/12/10)
Rey Mysterio vs. Mike Knox (Superstars 2/18/10)
Rey Mysterio vs. Tyson Kidd (Superstars 3/25/10)
Chao Guerrero/Zack Ryder vs. Evan Bourne/Yoshi Tatsu (Superstars 4/8/10)
Chris Masters vs. Dolph Ziggler (Superstars 5/13/10)
John Cena/Evan Bourne vs. Edge/Sheamus (Raw 5/17/10)
Rey Mysterio vs. The Undertaker (Smackdown 5/28/10)
Rey Mysterio vs. Jack Swagger (Smackdown 6/11/10)
Drew McIntyre vs. Matt Hardy (Smackdown 6/23/10)
Christian vs. Drew McIntyre (Smackdown 7/16/10)
Christian vs. Drew McIntyre (Smackdown 7/30/10)
Chris Masters vs. Chavo Guerrero (Superstars 8/12/10)
Christian vs. Drew McIntyre (Smackdown 8/20/10)
Goldust vs. William Regal (Superstars 8/26/10)
Christian vs. CM Punk (Smackdown 9/17/10)
The Undertaker vs. CM Punk (Smackdown 10/1/10)
Rey Mysterio vs. Alberto Del Rio (Smackdown 10/8/10)
As you can probably tell I think Christian and Rey especially had excellent years with several really good matches, and a higher consistency than almost anybody. Definitely two of the best wrestlers in the world at the time to me, even if they aren't terribly well represented in my top 25 because of higher peaks out of Japan and Mexico. If it was US-only then half my list might be those two alone. I honestly prefer a lot of these WWE tv matches to almost anything out of the US indies in 2010.
