The Panthers signed second-rounder Kawann Short earlier today, and finished up the defensive tackle double-dip this afternoon.
According to a Twitter message from his agents, first-rounder Star Lotulelei has agreed to his deal with the Panthers.
His ability to play the run will be key for the Panthers defense this year, and should help a group of mobile linebackers to flow more freely to the ball.
While many teams sign picks from the later rounds and work their way up, the Panthers now have deals with the first two of their five.
