Richardson, the team's top draft choice as a second-round selection out of Colorado, garnered 30 percent of the vote to finish ahead of UCLA defensive end Cassius March, a fourth-round selection who received 24 percent of the vote.
Richardson is a burner who has consistently been time in the 4.4s for the 40. He showed his blazing speed on the first day of rookie minicamp when he caught a couple of deep throws for touchdowns.
Wide receiver Chris Matthews, the 2012 CFL Rookie of the Year who was signed by Seattle earlier this year, also received a few votes.
Third in the survey was offensive tackle Justin Britt, a second-round choice from Missouri, who ended up with 16 percent of the vote. Alabama receiver Kevin Norwood, a fourth-round pick, received 11 percent of the overall vote. Outside linebacker Kevin Pierre-Louis, a fourth-round choice from Boston College, got 8 percent of the vote.
The other player receiving a couple of votes was fullback Kiero Small, a seventh-round pick from Arkansas.
