Pettis captured the UFC lightweight title with an armbar against Henderson.
A decorated jiu-jitsu black belt, Demian Maia would likely beat many fighters on this list in a pure grappling match. Nonetheless, his jiu-jitsu credentials haven't completely translated into MMA submission prowess over recent years.
Maia's neck crank against Rick Story at UFC 153 was his first submission in nearly five years.
Still, he has earned half of his 18 MMA victories with submissions. The Brazilian began his UFC career with five straight submission wins, including a triangle choke against Chael Sonnen.
Antonio Rodrigo Nogueira
"Big Nog" might be the best heavyweight submission artist in MMA history.
However, we're talking the best submission fighters today, and Antonio Rodrigo Nogueira's most recent submission victory over an elite opponent came in his February 2008 bout with Tim Sylvia. Since then, the Brazilian has only submitted Dave Herman.
With 21 submission wins in his MMA career, Nogueira is still a threat against anyone who goes to the ground with him, but the former interim champion no longer possesses the most feared submissions in the heavyweight class.
Like Nogueira, BJ Penn's exclusion from this top-10 list is a "what have you done for me lately" situation.
The Hawaiian has not even competed inside the Octagon in over 12 months. Moreover, his most recent submission victory came against Kenny Florian in August 2009.
Penn is ready to make a return to fighting through a coaching stint on TUF 19. Once he gets back to competing, Penn will still be considered a serious danger on the ground.
Judging by his performance against Benson Henderson at UFC 164, Anthony Pettis could be headed on his way into this top 10 in a hurry. However, aside from capturing the UFC lightweight title with an armbar in August, Pettis hasn't submitted many high-level opponents.
Pettis has scored seven submission wins over the course of his career, but the next most notable opponent he tapped was Shane Roller.
The only fighter to submit Henderson since March 2007, the 26-year-old Pettis is likely to have many more submission victories ahead.
While Anderson Silva's striking has stolen the thunder in most cases, "The Spider" wouldn't have reached the heights he has without his grappling ability.
The former middleweight champion defended his belt twice with submissions. It would have been three times had Travis Lutter made weight prior to UFC 67. The most notable of those submission wins came against Chael Sonnen, who was less than two minutes away from dethroning Silva before the Brazilian caught him in a triangle choke.
Although Silva is no longer champion, he'll have a chance to regain his crown at UFC 168, where his submissions could be a factor against talented wrestler Chris Weidman.
