9. BJ Penn
In his heyday, BJ Penn truly lived up to his nickname of ‘The Prodigy’ with 11 of his 12 UFC victories having come inside the distance.
Part of the key to the former lightweight and welterweight UFC champion’s success was that he was dangerous both as a striker and on the mat, registering seven Octagon wins by strikes and five by submission.
The vast majority of Penn’s finishes came at lightweight, including an 11-second KO of Caol Uno, along with other stoppages of Din Thomas, Sean Sherk, Kenny Florian, Diego Sanchez and Jens Pulver, to name a few.
The Hawaiian legend also proved he could finish fights at welterweight as well, stopping one of the division’s all-time greats in Matt Hughes twice in the first round; once by KO and once by submission.
