Official” 2013 Senior Bowl Practices Review
South DL

Senior Bowl Executive Director Phil Savage breaks down their individual performances including their pass rush wins and losses and then ranks them in order based on the Monday through Wednesday practices only.
1. #83 Cornelius Washington/Georgia
DE 6040/264 33 7-8” arm/9 1-4” hand
Cornelius played multiple positions in Georgia’s 3-4 package, but at the Senior Bowl, he lined up at defensive end all week. With one assignment in mind, to get upfield and create pressure on the QB, he accomplished his goal by showing initial quickness, strength and effort. He took the fight to his opponents by screaming off the edge and attacking with his hands.
There is no doubt that the 4-3 teams will go back and give him another look after this performance. He has the frame, long arms and motor to contribute as a Sub rusher in his rookie season. Cornelius elevated his stock from late-round flyer to legitimate mid-round candidate. He has the tools for a quality defensive line coach to develop very quickly.
1-on-1 Pass Rush- Wins: 6 Losses: 2
Senior Bowl Scoop: After registering only a half-sack all season, in the Senior Bowl game, Cornelius tallied a tackle, a sack, a tackle-for-loss and forced a fumble in virtually two quarters of play.
