Literal Translation: Quality or Power of Turning ~ of Revolution ~ of Rotation.
In Fanatical Yankee's Deeply Demented & Twisted View of the FootBall World: A Defender's Capacity ~ or lack thereof ~ to Flip Hips or Turn & Burn in order to Mirror a prospective Receiver as he bolts DownField.
In Man Coverage, Core Strength and Combat Craft play a large role in a CornerBack's Success or Failure.
In Man Coverage or in Zone, you can be sure that Fluidity, Acceleration, Ball Skills, and ~ above all but Verticity ~ Processing Speed impact the Fortune of any CornerBack.
Run Defense is very important, as well.
...At least in my Perception.
But, above all, Processing Speed ~ Rapidly Reading & Reacting as the Play unfolds and ~ particular to Corners above all other Players ~ Verticity...are what carve out the difference between Pro Bowler and Putz.
Frankly, I don't give a rat's ass what a CornerBacks's "40" Time is.
And I care even less about'is "Ball Skills". Interceptions are nice, but just Gravy. The idea is to play Defense.
Verticity ~ Beautiful. Flips the Hips smoothly to Turn & Burn. And he's awesome in Press Coverage, as well.
Run Defense ~ Excellent. A real physical Player.
Provided he's healthy, I see Terry Hawthorne playing at an high level for a very long time.
