the attitudes about how to run training camp have also evolved - leading more teams to stay home. furthermore, restrictions dictated by the cba (nflpa) limit contact and prohibit such things two-a-days, which effectively reduces on-field activity during camp. with "organized team activities" ("otas"), mini-camps, and conditioning during the off-season, players remain in top physical shape year-round. the focus of training camp is no longer getting players back in shape, but more of fostering camaraderie and delving immediately into game prep.
