London said he was "humbled" by his players' commitment.
"I always ask them who do they play for," he said on Monday. "I don't want them playing for me. I want them playing for that individual or that cause or that person or that thing that said they couldn't be here or they couldn't succeed here, they couldn't make it here. Play for those things, play for those relatives, those people that are long gone or missed. Play for those type of ideas."
