"With Logan, obviously I have a history with him there in my time in New England,'' Robinson said. "He's a really smart football player, played a lot of different roles for the Patriots. He played outside corner, played inside corner. He's an aggressive tackler, good run-support player. He's a savvy coverage player, has a knack at the top of the route, end of the route.

"He has been one of the more productive corners … over his career there in New England."

A third round (83rd overall) draft pick by New England in the 2013 NFL Draft, Logan started all 16 games for the Patriots last season, and finished with 92 tackles, 11 passes defensed and two interceptions.

In four NFL seasons, Ryan has recorded 243 tackles and 13 interceptions while playing in 64 straight games, with 40 starts. He tallied five interceptions for the Patriots in 2013, when Robinson served as director of college scouting with the Patriots.

Logan gives the Titans a top-notch cornerback in the secondary, and an experienced leader from a winning culture.

Logan (5-11, 195), who played at Rutgers, was the 16th rated cornerback by Pro Football Focus in 2016, and the fifth-best cornerback in tackle efficiency.

"He really had a similar, kind of a production resume at Rutgers," Robinson said of Ryan. "He had really good production on the ball in New England. He is a good teammate, a smart player. He is dependable, he is tough. He'll be a nice addition to the secondary with all those guys we have coming back that played quite a bit.
