Coach Harbaugh said the first day of football practice was like being born, a new start with lots of energy and people watching.
He said it was like leaving a warm, safe place and coming out into a bright, busy world.
One of the players, Derwin, agreed with Coach Harbaugh and said it felt like a new beginning for the whole team.
Another player, Justin, didn't talk about being born, but he said he was just happy to be playing football.
