So, did the skinny dork pay him for it?
He's a professional fighter, under contract with the UFC to fight for money on camera... you think they are going to just let him to go fight someone else for money on camera?
Seriously?
Its not like we will find the definitive answer, but pretty sure Strickland had to get paid to sparr someone while still under contract in some point of his career.
He is a prize fighter and this is like if Canelo went and sparr one of the Charlo brothers, i mean, they fight for money, it usually happens when both are pretty unknown, or the big name pays the unknown guy to do it, pretty normal, big names dont spar each other, not even for money as there is more money to be made with the real thing, here, the real thing cant happen as Strickland is under contract with the UFC, boxing match cant happen as they wont allow it, but, he seems to be able to spar whoever he wants, wether is the other guy going to him or Strickland going to the other guy, iirc, Eblem, Bellator MW champ has mentioned beating him in Sparring, probably when both were not so well known, or even recently but they didnt capitalized on it, cause well, they dont have a following behind, Jake Does, so its still a sparring session, one that can generate money but its still the same thing, UFC guys go do grappling, does the UFC have a problem with that? No, same for whoever they sparr with, Lomachenko sparred TJ Dillashaw...Both were champions at the time so money most likely was not exchanged, but footage was posted online, what else could Jake Paul do with it? a PPV session on Youtube? Conor already did that btw, he put an interview in PPV iirc, it can happen, the UFC doesnt have an issue with who the fighters sparr with, but its never at such level in names and "stakes", thats the whole difference here.
