What was the greatest win of B.J. Penn's UFC Hall of Fame career?

B.J. Penn, one of the biggest names in MMA history, returns to the cage on Sunday. As we get ready for the return, let’s look back at his impressive career so far.

More specifically, let’s try to determine one thing: What was the biggest moment of his illustrious career?

On Sunday Penn (16-10-2 MMA, 12-9-2 UFC) fights for the first time since 2014 – and looks for his first victory since 2010 – when he takes on fast-rising featherweight Yair Rodriguez (8-1 MMA, 5-0 UFC). Their bout headlines the FS1-televised UFC Fight Night 103 event at Talking Stick Resort Arena in Phoenix.

Penn is on a three-fight skid and is just 1-5-1 since early 2010, but a victory over Rodriguez, who’s an honorable mention in the USA TODAY Sports/MMAjunkie MMA featherweight rankings, would certainly help revive his career.

Before the recent setbacks, Penn, who previously held UFC titles in two different weight classes, was one of biggest draws in MMA. He was also one of the most naturally gifted competitors in the cage.

Ahead of his return, the UFC has released “B.J. Penn – Ultimate 8,” in which UFC commentator Joe Rogan lists the top eight moments from the 38-year-old Hawaiian’s accomplished career.

It’s an impressive list with some dazzling performances, but the top spot goes to his UFC 46 win over Matt Hughes. In the rivals’ first meeting, Penn picked up his first UFC belt – at welterweight, not lightweight – with a dominant performance over an MMA legend (one in the prime of his career) at the 2004 event.

Check out the performance, as well as other career highlights, above.
