The Steelers signed Jon Bostic, who played last season for the Indianapolis Colts. Here's a closer look at the signing:
Grade: B. The Steelers stayed away from the expensive linebackers in the $5-to-$9-million-per year range and opted for a journeyman veteran who capitalized on a starting chance in Indianapolis with 97 tackles and a sack. Bostic, who agreed to a two-year contract, will be viewed as a good stopgap to replace Ryan Shazier until a draft pick develops.
