Maybe they thought Floyd was going to do the same thing he did with McGregor. Carry him through the fight, and then Floyd would end it. Maybe that would've helped Tenshin's brand. However, Floyd was paid significantly less for this so he had no intention of carrying anyone.
It probably drew lots of viewers, but damaged Tenshin's star power. Their other star, Kyoji Horiguchi, looked great though. Knocked down an American champion multiple times, he choked out the heavier, taller, bigger, stronger American in Darrion Caldwell and is now a dual champion.
