The San Francisco 49ers, after agreeing to a blockbuster trade-up, took a blowtorch to every 2021 NFL mock draft created beforehand. General manager John Lynch sent two future first-round picks and a 2022 third-round pick to the Miami Dolphins to swap their 2021 No. 12 overall pick for Miami’s No. 3 overall pick, all but ensuring that head coach Kyle Shanahan will have a new rookie quarterback on his roster this upcoming season. The Dolphins proceeded to trade a 2022 first-round pick, a 2021 fourth-round pick and the No. 12 selection in 2021 to the Philadelphia Eagles for the No. 6 pick and a fifth-rounder. Miami reenters the top-end wide receiver market (Ja’Marr Chase, Jaylen Waddle, DeVonta Smith) with the second trade, while Philly trades six draft order spots for a future first-rounder to help build around second-year signal-caller Jalen Hurts (for now).
