When I worked out with the Panthers, they just wanted me to run the route tree. It's kind of different with college and pros. Some teams want the speed out instead of just chopping the feet, or when you're running a dig route they want you to speed cut it in. The Panthers want a spear route. We had a nice conversation, and then we went in the receivers room and drew up some coverages. They told me they really like me and hope I won't get picked before they pick me.
Take it FWIW, lock if old.
