The Green Bay Packers' 2018 draft began on Thursday night with a trade down from No. 14 to No. 27. But they weren't done making moves. Not long after, the Packers moved up from No. 27 by swinging a trade with the Seahawks to assume control over the No. 18 pick, which they then used on cornerback Jaire Alexander out of Louisville. 

According to ESPN's Rob Demovsky, the Packers got the 18th pick and No. 248 (seventh round), while the Seahawks acquired the No. 27, No. 76 (third-round), and No. 186 (sixth) picks. News of the trade was first reported by NFL Network's Ian Rapoport.

It's been a busy opening round for the Packers, whose night began when they agreed to send the 14th pick to New Orleans in exchange for the 27th pick, the 147th pick (fifth round), and a 2019 first rounder. The Saints then used that pick to take edge pass rusher Marcus Davenport. The Packers weren't content sitting at the end of the first round, engineering a trade with the Seahawks -- a team that always loves to trade back for more draft capital -- to move up and take Alexander.

In Alexander, the Packers are addressing a need of theirs -- CB1: Kevin King, CB2: Tramon Williams -- by drafting a cornerback with their top pick for the second straight year. Last year, they took King in the second round. This year, they took a cornerback who notched seven interceptions and 15 passes defended in his three-year career at Louisville. Pete Prisco gave the Packers an "A" grade for the pick, writing: "They get a smooth cover player who plays with a swagger. They wanted a corner and get a darn good one."  Meanwhile, CBS Sports draft expert Chris Trapasso highlighted Alexander's "exceptional mirroring skills," his ability to play zone coverage, his aggressiveness "at the catch point," and his "football IQ and athleticism."

Last year, the Packers' defense ranked 26th against the pass, according to Football Outsiders. This offseason, they hired a new defensive coordinator in Mike Pettine, who will replace Dom Capers, and traded away cornerback Damarious Randall. So, it'll be a new-look defense for once in Green Bay.

From the Seahawks' perspective, they certainly needed more draft ammunition to fill in a roster that got gutted.

You can't say Pete Carroll didn't warn us about a trade:
