Organized Team Activity (OTA)

Organized team activities (OTAs) are what professional football teams hold during the off-season. They are usually training sessions where teams learn the playbook and the techniques of their positions; hard-hitting is usually banned.
 
“There’s even something called organized team activity (or OTA)—best described as a relaxed ‘mini’ minicamp” was cited in print in June 1998. The “mini-camp” is another program that football teams hold during the offseason.

Organized team activities
Recently the NFL has let teams have off-season training sessions, officially called “organized team activities” (OTAs). Many teams use the OTAs to help develop players and make them better. These training sessions are in late April and early May. The OTAs are the only practices between the end of the previous season and the start of training camp. Players new to the NFL attend seminars and lectures organized by the NFL from mid-June to mid-July. For veteran players, they use the off-time to sponsor football camps for children, golf outings for charity, or even some family time.
