The Seattle Seahawks' official offseason program has not yet begun, but Russell Wilson and a couple of the team's wide receivers are working out together at USC.

The wide receivers pictured are Tyler Lockett and Paul Richardson.

Lockett is coming off a tremendous rookie season in which he caught 51 balls for 664 yards and six touchdowns. He was also a weapon on special teams, scoring two more times -- once on a punt return and once on a kickoff return. The Seahawks play a lot of 11 personnel (one RB, one TE, three WRs), and even though Doug Baldwin and Jermaine Kearse project as starters, Lockett will be on the field plenty in his second season.

Richardson, meanwhile, has a more uncertain role. A second-round pick in 2014, he dealt with a hamstring injury last year and caught just one ball for 40 yards. With the Seahawks having re-signed Kearse during free agency, Richardson could have a tough time finding snaps, barring an injury to one of the top three wide receivers.

But like everyone else, he'll try to compete for playing time during camp in the spring and summer.
