Contrary to what many think, Cam can't be calm on the sideline. He's constantly cheering, running, jumping, everything!
Letting him stay home is the best way to protect him from himself.
He genuinely loves the game and the comraderie that comes with being on a team. He's a big ole kid that just loves football. Some might want him to be more mature (subdued) and dress professionally. Personally love his enthusiasm. It's refreshing in today's big money business of the NFL.
