This upcoming Draft is not about 2021, but 2022. According to Greg Bedard of Boston Sports Journal, the Patriots have 29 Free Agents in 2022. I don’t feel all 29 players will make the 53 man roster, but that is almost as many players in a contract year as they had last year. They will have $160K tied up in contracts for 2022 and the Cap is expected to $200M in 2022. So they won’t have the money available to sign Free Agents that they had in 2021.
Don’t expect any rookie draft pick to have any impact on the 2021 team.
