The Pittsburgh Steelers made a big splash on Tuesday by signing free agent safety Mike Mitchell to a five-year, $25 million deal. Mitchell brings youth to a defense where the average age of the starters was 33 last year.
I give this signing an A if I have to grade it. Mitchell had a breakout year in 2013 on one of the NFL’s best defenses. He also came at a pretty good price for the Steelers.
