NFL OTAs are organized team activities. They're essentially an informal summer practice that takes place before training camp really heats up in August.'
Technically, speaking OTAs are a voluntary activity. However, when you consider that most teams carry a summer roster of nearly 100 players, competition for the eventual 53 spots is fierce right out of the gate.
