The Dolphins made two blockbuster trades on Friday, first with the 49ers and then with the Eagles, and those two trades resulted in the draft picks that will shape Miami’s roster for years to come. But those trades couldn’t have happened without a previous blockbuster trade.

That was the Dolphins trading left tackle Laremy Tunsil to the Texans, acquiring picks that included the No. 3 overall pick that Miami just sent to San Francisco.

In that trade, the Dolphins sent Tunsil to the Texans in exchange for Houston’s first-round pick in 2020 and first- and second-round picks in 2021. (Houston also traded offensive tackle Julién Davenport and defensive back Johnson Bademosi to Miami, while Miami also sent wide receiver Kenny Stills, a 2020 fourth-round pick and a 2021 sixth-round pick to Houston, but the headline was Tunsil for two firsts and a second.)
