CB Cox flashes instincts on Day 3

MOBILE, Ala. -- Practice has wrapped up on Day 3 of Senior Bowl week and several players stood out. Here's a look at who had the best days and those who struggled, and the things we heard and saw that could affect the draft stock of several prospects.

South Team: Good Days

Oklahoma State CB Perrish Cox -- Cox did a nice job staying low in his backpedal and opening his hips during individual work. That allowed him to make interceptions on back-to-back plays during the team period. On the first play Cox stuck in UAB WR Joe Webb's back pocket, anticipating the route and making a nice catch in traffic. On the second he got good depth in his drop and read the eyes of college teammate Zac Robinson before closing on the ball quickly and snatching it out of the air. Cox looked smooth in and out of his cuts all day, showing fluidity and exploding out of his pedal when breaking on the ball.
