Following his crushing first round technical knockout loss at the hands of Alistair Overeem in the main event of UFC 141 in Las Vegas last night, Brock Lesnar announced his retirement from MMA.

No doubt his absence from future fight cards will deal a decidedly large blow to the pocketbooks of those in command of the world's largest fight promotion. But when it's time to go, it's time to go. Or, as UFC President Dana White put it, "guys know when it's time to retire."

Indeed, Lesnar has been suffering through medical issues for years now, including a bout with diverticulitis that forced him to undergo surgery to remove 12 inches of his intestines earlier this year. It's hard enough fighting the best heavyweights in the world. Dealing with faulty equipment while attempting to do so is an exercise in futility.

And so, the Brockness Monster retreats to the cold, blistery confines of his home in Minnesota to enjoy his time with his family. But there's one man who doesn't want to see him go.

The man who sent him on his road to retirement, "The Reem." From the UFC 141 post-fight press conference:

"I think he shouldn't walk away. Because, love him or hate him, but it's always something when Brock's fighting, like Dana said. I mean, he's a guy who goes for it. I think he achieved a lot in a short span and yeah, it would be a shame if he stops now. I think there's still more to gain for him."

There's no questioning the fact that Lesnar accomplished a lot in the short amount of time he was involved in the sport. He signed a deal with the UFC in 2008, won the heavyweight championship that same year after just two fight with the promotion and successfully defended it twice over the next two years.

But once he was hit with diverticulitis he was simply never the same.

Cain Velasquez embarrassed him in the first round of their UFC 121 fight to take the 265-pound title and now Overeem has done the same at UFC 141 just over a year later, taking his last chance to earn a crack at winning it back.

Really, this seems like the proper time for Lesnar to call it quits. Does he have more to gain in the sport? Overeem says he does but it doesn't quite seem that way to me.

Maniacs, what do you think?
