The CBA only permits the team to do so much during the first five days of TC.
(a) The first day of a Club’s preseason training camp shall be limited to physical examinations, meetings, and classroom instruction; no on-field activities shall be permitted other than running and conditioning. On-field activities are limited to Phase One-type conditioning, timing and testing, except that all coaches are permitted on the field. No helmets or protective shirts are permitted. No footballs may be used (“dead ball” activities only). No plays or walk-throughs are permitted. No individual player instruction or team drills are permitted. Nothing shall prohibit a Club from administering a conditioning test provided that such test must be reasonable and appropriate to determine the player’s ability to participate in the individual and team drills permitted by this Article. No such test may be given solely for the purpose of disciplining a player who reports to preseason training camp out of shape or overweight.
(b) (b)(i) On days two through five of preseason training camp, no live contact shall be permitted. Players may be on the field no more than 3.5 hours. Two on-field sessions are permitted as follows: one session may be a full speed practice, which can be no longer than 2.0 hours. This session may include all customary practice activities at the head coach’s discretion. The other session on the same day may be for a maximum of the remaining 3.5-hour on-field time, and is limited to only walk-through instruction and drills and plays conducted at an acceptable walkthrough pace (i.e., Pro Bowl practice pace), as demonstrated in a video jointly approved by the parties, with offensive players lining up across from defensive players, or kicking team players lining up across from return team players. No helmets may be worn during the second practice. The two on-field practices may be conducted in either order.
(b)(ii) On days two and three, helmets and jointly-approved protective shirts are permitted for the full speed practice.
(b)(iii) On days four and five, helmets and jointly-approved protective shirts, shells and spiders are permitted for the full speed practice (shells and spiders shall be jointly approved by the parties).
