A look at a memorable moment in Seahawks history that occurred on April 13:
2010: Patrick Kerney announces his retirement after 11 seasons in the NFL and three with the Seahawks. The defensive end from the Falcons was the Seahawks' big free-agency addition in 2007, and Kerney led the NFC with 14.5 sacks and was voted to the Pro Bowl that season. He also led the Seahawks in sacks (five) in 2009.
