The Cleveland Browns are set to begin their offseason programs on April 20th, leading up to the 2015 NFL season. A few teams begin their programs two weeks earlier, but those are only teams with new head coaches. Monday, April 20th begins "Phase One" of the team's offseason program. According to the CBA, that consists of the following:
Phase One shall consist of the first two weeks of the Club's offseason workout program. Phase One activities shall be limited to strength and conditioning and physical rehabilitation only. During Phase One, only full-time or part-time strength and conditioning coaches, who have no other coaching responsibilities with the Club, shall be allowed on the field; no other coaches shall be allowed on the field or to otherwise participate in or observe activities. No footballs shall be permitted to be used (only "dead ball" activities), except that quarterbacks may elect to throw to receivers provided they are not covered by any other player. Players cannot wear helmets during Phase One.
Only the Browns' strength and conditioning coaches would be allowed on the field. More coaches can start getting involved when minicamps and organized team activities commence, per the schedule below:
OTA Offseason Workouts: May 26-27, May 29, June 1-2, June 4, June 8-9, June 11-12
Mandatory Minicamp: June 16-18
