Still, Walker doesn't believe his time in MMA is over just yet. Speaking on the Lavar Arrington Show, Walker expressed interest in competing in MMA one more time. Walker also emphatically expressed his desire for the fight to take place in the UFC's Octagon.
Internet message boards lit up about speculation of Walker joining the UFC's ranks. Both sides of the argument have presented worthy causes but Dana White should definitely consider the idea of bringing Walker in.
There are a number of benefits that the UFC could and should take advantage of by bringing in the football great.
We all know the UFC isn't into freak show fights like some past MMA promotions, but bringing Walker isn't a freak show attraction.
Now don't get me confused I'm not saying he's great MMA fighter, but the man does have a pretty outstanding background in martial arts. Walker is a fifth-degree black belt in tae kwon do and has competed in numerous martial arts tournaments during his athletic career.
Walker does own two victories in MMA and of course they were "gimme fights," but they were still on the world's second biggest stage at the time.
He's not going to make a run at a title or be a force in the UFC, but he's certainly able to handle himself in the cage.
One name that's come up quite a bit in the Walker discussion is James Toney.
The former boxing champion made headlines by literally stalking White across the country, attempting to get in the UFC. When White finally accepted the offer, Toney was embarrassed by MMA legend Randy Couture.
Toney was a good boxer at one point in time, but those days had clearly passed by the time he stepped into the Octagon.
The move was a clear attempt to grab some headlines while the UFC attempted to prove MMA's supremacy over boxing.
Walker is 51, but is and always has been an athletic freak.
You don't have to worry about Walker coming in out of shape or not prepared to compete. Also, Walker wouldn't be training with a hand picked camp of "yes men" like Toney, but would likely head back to AKA where he's trained before.
If the UFC can bring in an over-the-hill, out-of-shape boxer with no MMA fights or experience to compete, what's the problem with bringing in a martial artist who's still in great shape?
I don't know about you, but I'm getting tired with all these safe and conservative strategies employed in the UFC.
I understand guys want to fight smart but the keyword is fight. I fail to see how doing nothing more than laying on someone or circling around the cage while landing a few strikes qualifies as MMA.
Walker wouldn't have to worry about that because he knows he's only in it for one fight.
Add that to Walker has nothing to lose both athletically or financially and I'd expect Walker to at least bring some offense to the cage.
People will of course mock his "arm-pit finish" and sluggish performance in Strikeforce, but at least we know Walker's competitive spirit wouldn't let him coast to a decision victory.
He doesn't have to fear being cut by the UFC or ruining his MMA career by losing and has everything to gain with nothing to lose by leaving it all in the Octagon.
One of the most obvious reasons to bring Walker into the UFC is for the headlines and media attention it would provide.
Walker is a football legend who would bring quite a few eyeballs to the Octagon and generate interest in the UFC.
Bernard Hopkins recently became the oldest boxer to win a major title, and while the two are nowhere near comparable, it's still relative to note how interested people were in seeing if the 48-year-old Hopkins could do it.
Much the same way fans tuned in to watch an aging Randy Couture or continue to cheer on a 42-year-old Dan Henderson compete, they would also likely follow Walker's story.
Aside from all the obvious storylines that are marketable for the UFC by bringing Walker in, there's also another story Walker could tell.
In his 2008 autobiography, Breaking Free, Walker claimed that he couldn't even remember the season in which he won the Heisman Trophy due to his diagnosis of dissociative identity disorder, more commonly known as "multiple personality disorder."
A lot of focus has been on mental health and the lack of treatment in America by major media outlets. Walker's story of how he copes with the condition and how he's overcame it only adds to the feel-good nature of his story.
Fox Sports 1 is the current golden child of Fox and it's clear the network will be making a run at the throne of ESPN in the sports world.
The UFC figures to play an important role in helping Fox achieve that goal and there are extensive plans in the works for UFC programming and Fox Sports 1, including a Super Bowl fight card.
Putting Walker in front of a camera on Fox Sports 1 would be a great marketing move for the UFC.
A recognizable figure with the football audience, Walker could provide not only a credible figure to draw interest from non-fans but also an articulate advertiser for the UFC.
Walker was all over ESPN and other networks when advertising for his appearances in Strikeforce and is quite capable of knowing how to talk with a camera in his face; a trait not common with many fighters in the UFC.
