And one of the big decisions is whether to address positions of need via the 2021 NFL Draft, the upcoming free-agency period or the trade market.

Teams assess their weaknesses and look at all potential options in a given position group. In this series, we’ll investigate the strengths and weaknesses of all positions this offseason, with an eye toward the draft, free agency and the potential trade options.
