"That's all I've really been thinking about. I'm happy to play in it, but I want to win the game. I feel like once we get there it will sink in even more.
"The energy, there is a lot of energy. We just want guys to be focused. That is the main thing Coach has been talking about and Peyton [Manning] has been talking about, being focused.

Thomas was drafted by the Broncos in the first round in 2010.
