UFC Fight Night: Khalil Rountree vs Karl Roberson Preview

A clash of high level strikers takes place on the main card of UFC Fight Night: Santos vs Ankalaev between Karl “Baby K” Robertson and Khalil “The War Horse” Roundtree on March 12 at the UFC Apex Arena in Las Vegas, Nevada in the Light Heavyweight Division.

Has Khalil Rountree learned some new tricks?

Khalil Rountree (9-5; 1 No Contest) enters this fight off of an impressive win via side kick to the knee against Modestas Bukauskas. That fight was the first time a fighter has won a fight by kicking the lead leg, which started an outcry to ban the kick after Roundtree won. The technique involves a downward sidekick to the opponent’s lead knee as he is coming forward, which has the potential to seriously injured the ligaments. However, there have been no changes to the rules yet, so let’s see if Khalil will explore the same tactics against Karl Robertson

Can Karl Roberson find success after moving up in weight?

Karl Roberson (9-4) could be fighting for his job as he is coming in on back to back losses to Marvin Vettori by first round rear naked choke and then to Brendan Allen by round one heel hook. Roberson is a high level kickboxer who has fought over in Glory Kickboxing. Because not a lot of fighters want to stand with him, he has historically struggled versus bigger grapplers with all 4 of his losses coming by way of submission. Furthermore, Roberson is moving up in weight and taking this fight at Light Heavyweight and not at Middleweight, where he has fought most of his UFC fights. The last time he fought at Light Heavyweight was in January 2019 where he was submitted by the current Light Heavyweight Champion, Glover Teixera.

UFC Betting Trendsย  โ€” Rountree vs Roberson

Khalil Rountree

  • Rountree has not gone to decision in 6 of his last 7 UFC fights
  • Rountree has not attempted a takedown in his UFC career

Karl Roberson

  • Roberson has been taken down in all 4 of his losses
  • Roberson has outstruck his opponents in all 5 of his UFC wins

Free UFC Picks โ€” UFC Best Bets For Rountree vs Roberson

Both fighters, Roberson and Rountree, are fairly similar fighters in that they are both southpaw strikers who like to mix in punches and kicks. Both guys want to keep the fight standing and have struggled versus grapplers. Physically, both fighters are the same age at 32, and both stand 6’1″. Rountree will have a slight 2″ reach. Rountree is the busier fighter landing 3.24 strikes per minute, but also absorbs 3.58 strikes per minute. Roberson is a little less busier landing on 2.87 strikes per minute, but also only absorbing 2.38 strikes per minute.

The main difference between the two can come down to cardio and chin. I favor the cardio of Roberson as Rountree has slowed down in fights, but again it’s worthwhile noting that this fight should stay on the feet without a ton of grappling. With that said, I also favor Roberson’s chin. He absorbs fewer punches and has also never been knocked out or lost a decision, where as Khalil Rountree has had 2 of his last 3 losses come by first round knockout. One other note worth mentioning is that the last time Rountree fought a fellow southpaw was against Ion Cutelaba where he was knocked out. The last fight Roberson fought a southpaw was against Kopylov where he won by submission.

Here’s how I see the fight playing out:

  • Roberson by TKO/KO: 30% (+233 or better)
  • Roberson by submission: 5% (+1900 or better)
  • Roberson by decision: 20% (+400 or better)
  • Rountree by TKO/KO: 20% (+400 or better)
  • Roundtree by submission: 5% (+1900 or better)
  • Rountree by decision: 20% (+400 or better)

Which translates to:

  • Karl Roberson -122 or better
  • Khalil Rountree +122 or better
  • Fight goes to decision: +150
  • Fight does not go to decision: -150

I think the current odds are about right with Roberson around -125. All of the early value on Roberson is gone now that the line has moved. I’m picking Roberson to win, and may place small moneyline bet on Roberson after I see how they match up at weigh-ins. The fight to end by submission is +600, which could yield some value noting that all 4 of Roberson’s losses have been by submission and 4 of Roberson’s last 6 wins have also been by submission.
