The Eagles wanted Agholor & turned down a chance to trade 1st round picks and add picks from Denver.— Gil Brandt (@Gil_Brandt) May 16, 2015
Chip Kelly and the Eagles went on to select USC wide receiver Nelson Agholor with the 20th overall pick in the 2015 NFL Draft.
The Broncos did eventually trade up the Detroit Lions three picks later and selected Missouri pass rusher Shane Ray with the 23rd overall pick in the draft. The Broncos sent the 28 overall pick, a fifth-round pick (No. 143), a 2016 fifth-round pick, and former starting center/guard Manny Ramirez to the Lions.
If the Broncos were to trade up to the 20th overall pick they probably would have at least given up their 3rd round pick in 2015, and multiple late round picks in 2015 and 2016.
Now to the bigger question here, who were the Broncos targeting at 20? The most logical guess here is former Texas A&M offensive tackle Cedric Ogbuehi. He was selected by the Cincinnati Bengals with the 21st pick.
A few days before the first-round of the draft, Sports Illustrated's Peter King mocked Ogbuehi to the Broncos and said that the Broncos "love Ogbuehi". So it makes sense that they were targeting the very athletic Ogbuehi in this potential trade up in the first round.
The Broncos did get their offensive tackle in the second round when they selected Colorado State offensive lineman Ty Sambrailo with the 59th overall pick.
