Chicago Bears release Isaiah Frey

Isaiah Frey was just released per source.

I only say surprising because Frey had arguably his best day as a pro last Sunday against the Carolina Panthers.

Frey's release leads me to believe that cornerback Sherrick McManis is ready to play this week after nursing a quad injury the last few weeks.

Then again, perhaps the Bears are ready to try rookie safety Brock Vereen at the nickel position.

Or... Maybe the Bears plan to call veteran defensive back Kelvin Hayden, who turned down an offer to return a few weeks ago.

One more option for the Bears is Demontre Hurst, whom they brought back on September 18th. He was playing some nickel in camp and preseason.

I think the best plan would be for the Bears to use McManis in the same role they envisioned for rookie Kyle Fuller. If you remember the original plan was to use Fuller on the outside in nickel packages, with starting corner Tim Jennings moving inside to play nickel. The injury to Charles Tillman forced Fuller into a starting role, a role he's thrived in so far. Fuller was the defensive rookie of the month for September.

What are your thoughts on this move?
