When the scouts saw that DK Metcalf ran the three-cone drill as he did... his stock dropped like a rock. Consider this, Metcalf was in the bottom 3% of players who have run the three-cone in the last 25 years. The guy can basically run three routes and most of that is a straight line. He may look like Tarzan, but he runs routes like Jane.
The Bills already have Robert Foster, John Brown. I could see them going Irv Smith. Lots of good players still on the board and I'm hoping they go offense with the next pick.
