The Detroit Lions have announced the signing of all nine 2013 draft picks. Defensive end Ziggy Ansah, cornerback Darius Slay, guard Larry Warford, defensive end Devin Taylor, punter Sam Martin, wide receiver Corey Fuller, running back Theo Riddick, tight end Michael Williams and linebacker Brandon Hepburn all agreed to four-year deals. Ansah is just the second first-round pick, and first in the top 10, to already agree to terms on a deal. The team did not disclose the terms of the contracts, but those numbers can be accurately projected based on the league's rookie salary scale. The Lions are scheduled to open up rookie minicamp on Friday. All eyes figure to be focused on Ansah.
