The St. Louis Rams have agreed to terms with Eagles S Quintin Mikell. The news was first reported by ESPN's Adam Schefter. Mikell has a connection to Rams head coach Steve Spagnuolo; he played under Spags when he was a defensive coach in Philly.
Mikell has agreed to a four-year deal, the terms of which are unknown at this time. How much Mikell is getting paid could be big as the Rams have precious little salary cap space. Mikell's addition likely spells the end for S James Butler, who is due to $3 million in salary this year. That should pay for a healthy chunk of Mikell's salary, but doubtful it pays for all of it as Mikell was one of the top safeties available on the market this year.
Pro Football Focus had Mikell as their top rated safety last year. Mikell is the prototypical Spagnuolo safety, strong in coverage, can play in the box. I don't know that I'd call it an upgrade over Atogwe, but it's different to be sure. He's a better fit for this defense than a pure centerfielder.
