Floyd knows you are a long time retired in professional sports, he is only 30 and has two good years and at least 4 maybe 5 big paydays ahead of him. He isn't going anywhere just yet, his ego won't allow it for a start! Losing to Oscar won't bother him to much as he will go back to 147 and clean up down there!
He's thinking legacy right now, he gets it by beating Oscar or unifying the Welter belts.
