Come on guys, there is no need to make theories and speculate a lot about Zuckerberg in Volks corner. It was done mostly for media purpose. Mark wanted to be more close to a sport he is interested in. Dana and UFC got some extra media recognition. If there is a chance to let famous person to be close to action, why not? It only plays good for business. He did not interfere, he did not do anything bad. He just stood and watched. And media posted most attracting attention photo of him. Of course there are million more photos of him, from every angle.
P.s. To bad from any angle he looks the same. The same as Madame Tussauds weird wax figure

If there is no given fact about it then people will tend to speculate even though I am stretching my head after seeing it but my mind just overflows with so much information thinking on what Mark Zuckerburg is doing in there, but yeah I think it is still viable to just say that Zuckerburg is just supporting Volk because he was in the corner, and not giving another statement that are just theories or hearsay.
Now I may skip the main event so sorry Jairzinho Rozenstruik but I am saving my bets for what I think are the best fights for this event and here are my picks for UFC Fight Night: Rozenstruik vs. Gaziev
Vitor Petrino vs. Tyson PedroFor this fight, the odds were 1.27 for Vitor Petrino the heavy favorite for this fight while 3.85 for Tyson Pedro for me Vitor Patrino is a solid striker and has power in it, right now I think that Petrino is good at his striking than Pedro, and Petrino is even wrestling a lot and you can really see that it is improving a lot every time he fights but Tyson Pedro can also knockdown Petrino we have seen him getting knockdown before but for me, his striking is absolutely great so my pick is Vitor Petrino.
Alex Perez vs. Muhammad MokaevFor this fight, the odds were 3.90 for Alex Perez and 1.26 for Muhammad Mokaev the heavy favorite for this fight, this is something even if you are just new to the UFC you will realize getting on board with the hype, but you are not wrong about it as I don't see the great fight for Alex Perez which he didn't show any great thing while Muhammad Mokaev is a beast and against Jafel Filho he has come back in the brink of getting his knee broken as he surely got a heart and turning the fight around so my pick is Muhammad Mokaev.
Umar Nurmagomedov vs. Bekzat AlmakhanFor this fight another Dagestani fighter, and the odds are 1.07 for Umar Nurmagomedov and the heavy favorite to win, 8.60 for Bekzat Almakhan for this fight Umar Nurmagomedov has decent striking, and with those kicks, he's got the range and we all know the wrestling of Dagestani should never be underestimated and he also got solid takedown defense I will be bias here for sure Umar Nurmagomedov will win this no doubt about that so my pick is Umar Nurmagomedov.
