Which NFL teams are using informal practices?

Informal practices are not only the rulebook for the game, they are also the lifeblood of a football team.

While informal practices are meant to be short and to keep the players and coaches away from the field, they also can be the difference between a good day and a bad day for the team.

As a rule, the NFL is going to give informal practices the lowest of penalties, but they can be a major reason why a team is losing games.
