My observation exactly. He got rocked by those upper cuts and I thought he was down and out, but then I was amazed at how he shook it off in an instant and picked up the pace again, inflicting a lot of damage after that point. I thought the team was inspired more to seeing that there is no quit in Toots rather than to wether he won or lost.
Sugar Ray used to call it being in "The Dark Closet" when a guy gets rocked like that, and how most guys can never fight there way back out of the Dark Closet. I think Toots saw the lights flickering, and kicked it into high gear instead of letting himself get shut down. That's an amazing thing to witness. No Quit in Toots, that's for damn sure.
It was hard to say for sure, but it looks like about all of those upper-cuts missed, grazing off the left or right side of his face. I don't really think he was fazed all that much by it.
