After the 2014 draft ended, the defending Super Bowl champions signed an undrafted rookie free agent whose father won a couple of Super Bowl rings during his NFL career. Joining the Seahawks is Jackson Jeffcoat. The former Texas defensive end is the son of former Cowboys and Bills defensive end Jim Jeffcoat, who won championships with Dallas in 1992 and 1993. Despite speculation that Jackson Jeffcoat would be moved to linebacker at the next level, the Seahawks list him as a defensive end, at least for now.
