Playing his position

Thomas is just excited to be here and happy to help out the team.
Yes, he is on the field in the middle of a game, although I didn't get any other players in the shot--probably because they were all, you know, PLAYING THE GAME at the time.

Sometimes Thomas does actually get involved in the game at hand.

Until he takes a ball in the crotch and goes down hard, which he did right after this picture was taken. That tends to dampen his enthusiasm a bit.
