If I remember correctly, I had Till winning the first round, but it was mostly due to the flash knockdown. I remember it being competitive aside from that. I know I had Mas winning the second up until the KO.
That said, he might lose to Usman. If he does, is it really all for nothing though? The guy made a ton of money, finally got recognized for over 15 years of hard work, got an always desired title shot, got to have his childhood idol walk him to the cage for one of his biggest fights, got a belt wrapped around him by one of the biggest stars in Hollywood. His story will be one of success, even if he doesn't capture the belt.
I don't really see a lot of serious fans going around claiming Masvidal is the greatest thing since sliced bread. We know who he is, and we know what he is and is not capable of. He is a crafty veteran, who on his best day, can give anyone a tough night out. He's also a guy that, at least in the past, has forgotten where the gas pedal was, and gotten outpointed. However, there's no one in that division sitting there saying "man, Masvidal is such an easy fight, I wish he'd fight me." He's a tricky guy to fight, you gotta be on your A game.
He won't be a wash out if he doesn't beat Usman, he'll be a guy who lost to the champion of his division. He won't be the champion, clearly, but he'll still be a highly capable fighter, with even more notoriety.
