Seattle was originally scheduled to pick at No. 40 before making a second draft trade, this time with Detroit. By moving back five spots, the Seahawks were still able to get a speedy receiver to add to their roster and help make up for the loss of Golden Tate in free agency.
Seattle was thought to be looking for size from any wide receiver it might take. Instead, the Seahawks went for Richardson's raw speed to team with Percy Harvin as pass catching options for quarterback Russell Wilson.
Seattle moved down 13 spots from its originally scheduled first-round pick and added two additional picks. It was the fourth straight draft that Seattle made a trade in the second round.
Richardson missed the 2012 season with a knee injury. His rebound in 2013 was outstanding. Despite playing with a young quarterback, Richardson had a standout senior season with 83 catches for 1,343 yards and 10 touchdown catches. Three times he had at least 10 catches in a game, even as the Buffaloes were struggling through a 4-8 season.
The trade with Detroit also included a fifth-round pick sent to the Lions, but Seattle came out ahead picking up an additional fourth-round pick and a seventh-round selection.
Seattle originally moved down to No. 40 after trading the final pick of the first round on Thursday night to Minnesota. The Vikings selected quarterback Teddy Bridgewater. Seattle also had the final pick of the second round and is scheduled to have no picks in the third round.
The Seahawks also addressed their need to add depth to the offensive line by drafting Missouri tackle Justin Britt with the final pick in the second round of the NFL draft.
The offensive line appeared to be a need for the Seahawks heading into the draft with starting right tackle Breno Giacomini and guard Paul McQuistan leaving in free agency.
Britt was an all-Southeastern Conference first-team selection in 2013. Britt started all 14 games at left tackle last season, but played right tackle in the past for the Tigers. He's also projected to be able to move to guard as well and versatility has proven important for the Seahawks.
At 6-foot-5, 327 pounds, Britt started 36 of 49 career games at Missouri.
