Good read about trading down from Dan Labbe of cleveland.com
".....
When the Browns traded out of the No. 2 pick in 2016, they not only traded away the opportunity to pick
Carson Wentz, they also passed on a Top 5 that included, along with the quarterbacks, cornerback
Jalen Ramsey, defensive end
Joey Bosa and running back
Ezekiel Elliott. All have gone on to make Pro Bowls and, two years in, can already lay claim to being among the best at their positions in the entire league. The Browns, meanwhile, have yet to see a single true impact player anywhere near that level emerge from the picks they acquired. One of those picks, of course, as you work through the gymnastics of multiple other trades, is the No. 4 pick this year.
Those gymnastics include the No. 12 pick a year ago. The Browns, after selecting Myles Garrett No. 1 overall, traded out of that spot with the likes of safety
Malik Hooker and quarterback
Deshaun Watson on the board. Both players suffered season-ending injuries, but both the Texans and Colts have to be thrilled with the Browns' decision.
This isn't just a Sashi Brown problem. Ray Farmer traded down from No. 4 overall in 2014, giving up the opportunity to add the likes of
Khalil Mack, Mike Evans or Odell Beckham. Even Sammy Watkins, who has yet to live up to his Top 5 billing, would have offered more impact than Justin Gilbert, the player the Browns took in the end. ..."
