The good: In his first season with the Ravens, Miles finished third on the Ravens with eight special teams tackles despite not playing in the first four games. He joined the Ravens after being released by the Cincinnati Bengals. Miles had been one of the Bengals' top players on coverage teams, recording double-digit tackles on special teams in 2011 and 2012.
The bad: His biggest blunder came when we was flagged for being offside on a critical onside kick in Pittsburgh. He made the mistake even though he was running next to kicker Justin Tucker. Coach John Harbaugh called the error the "unforgivable part" of the play. Miles also has never developed as a safety.
The bottom line: The Ravens picked him up on waivers, which meant they paid him his restricted tender of $1.3 million last season. That tells me that the Ravens really wanted Miles to bolster their special teams. Miles isn't a priority in free agency, but I wouldn't be surprised if he ended back with the Ravens.
