Colorado Rapids head coach Pablo Mastroeni found a unique way to keep warm at Red Bull Arena on March 15, 2017.

For most if not all of his team’s 1-0 loss to the Red Bulls, the passionate coach marched up and down his coaching box, gesturing to his players and perhaps to officials while sometimes giving instructions.

While this small snippet does not do what Mastroeni demonstrated any justice (hey, we had to watch the game, not the coach), it does give you a slight insight into the world of at least one MLS coach.

Just wonder how animated he will be when he directs Real Salt Lake against the Portland Timnbers in the MLS Western Conference final today.
