Carder became the first Frog drafted by Buffalo since the Bills selected defensive end Aaron Schobel in 2001.
Carder recorded 228 tackles during his career at TCU while being named the Mountain West Conference Defensive Player of the Year in 2010 and 2011. In addition, Carder was also the Defensive MVP in the Frogs' 21-19 Rose Bowl victory over Wisconsin.
McCoy started 27 career games at TCU and was selected as the Mountain West Conference return specialist of the year in 2011 averaging 30.6 yards per kickoff return with two touchdowns. He was also named to the conference's defensive team as a corner racking up 32 tackles, 7 pass break ups and 2 interceptions.
Meanwhile, a third Frog was added to an NFL roster Saturday afternoon when the New Orleans Saints signed former defensive end Braylon Broughton to a free-agent contract. Broughton started five games in 2011, totaling 25 tackles and 6 tackles for loss. Broughton was one of the top performers at the TCU Pro Day, running in the 4.5's at 6-foot-4, 257-pounds.
TCU went 47-5 during Carder, McCoy and Broughton's four years on the team.
