The San Francisco 49ers opened up Phase 3 of the offseason workout program with a strong contingency of players on hand for the team's three days of organized team activities. Everything outside of the team's mandatory minicamp, which is slated for June 10-11, is voluntary for players, so the good turnout speaks to the "re-energized feeling around the facility" quarterback Brock Purdy spoke about last week following his contract signing. During Phase 3, teams may conduct a total of 10 days of OTAS, however, no live contact is permitted. Players can participate in 7-on-7, 9-on-7, and 11-on-11 drills.
