On days when padded practices are permitted under Subsection (a) above, on-field Team activity for all players shall be limited to a maximum of three hours per day, including “first period” (i.e., stretching and calisthenics), provided that (i) players may participate in on-field activities with their position coaches for a period not to exceed thirty minutes, prior to the three-hour maximum on-field period; and (ii) any walk-through of reasonable and customary duration (for purposes of this Subsection, such walk-through to be no helmets and acceptable walkthrough pace (i.e., Pro Bowl practice pace), as demonstrated in a video jointly approved by the parties) that is conducted prior to or after the three-hour maximum on-field period shall not count against that limit. The three-hour time limit described above shall begin as soon as position coaches begin to coach a player or players on the field, subject to provisos (i)–(ii) in this Subsection. On days when no padded practice is scheduled, on-field activities shall be subject to the rules set forth in this Subsection 1(d).
