Who needs 53 players anyway?

I guess I was not considering that both MM and V-Jax were going to consume a spot. And not that I'm bashing them but we have a few other guys on the team with very limited roles: David Binn the best long snapper in the history of the league. Darren Sproles a franchise player that returns punts. CBD a first round draft choice that does not get on the field much. These choices bring the Chargers 53 to 48. The team has decided to toggle a DL or DB weekly - I like. The team is keeping TWO quarterbacks - I don't like. The 2010 Chargers appear to be very vulnerable to injuries. The 2010 Chargers appear to have limited options if one of the 48 players does not play well. Maybe AJ is on to something here... Maybe NFL teams only need 48 players...
