First, every position should have some competition for backup roster spots.
==========
We have our starters from last year in Butler and Ryan. We drafted a nickel back with our first pick. Barring injury, these 3 should get 90% of the reps at corner.
==========
THE COMPETITION
is for the one or two backup roster spots. And yes, here there is real competition, and almost anyone could make the 53, including a free agent to be added later.
Maybe Roberts will be the best patriot coming back from spending his rookie season on IR since Ben Watson, maybe not.
Perhaps Coleman has a future, perhaps not.
One of the UDFA's may sneak in, or not. The Practice Squad should have 2 corners.
