The Jets and Giants went defense on Day 1 of the NFL Draft.

Days after securing a trade for one of the greatest quarterbacks of all time, the Jets failed to provide Aaron Rodgers with one of their offensive line targets. With the top four prospects at the position off the board, the Jets swerved and made a surprising reach, drafting Iowa State defensive end Will McDonald IV with the 15th overall selection.

McDonald, the first Cyclones player taken in the first round in five decades, wasn’t a lock to be taken Thursday night, but the pass-rushing specialist — his 34 sacks is tied for the all-time Big 12 record — can serve an immediate purpose for Robert Saleh and the win-now Jets.

The Giants made defensive coordinator Wink Martindale happy by trading up one spot with Jacksonville — giving up a fifth-round and a seventh round pick, in addition to the No. 25 overall pick — and selecting uber-athletic cornerback Deonte Banks of Maryland at No. 24.
