Titans free safety Michael Griffin wants to deliver more big plays, and the addition of veteran Bernard Pollard should free him up to do just that.

The Titans expect Pollard to make a big impact — literally. The former Ravens safety is known for jarring hits and physical play. He agreed to a one-year contract on Thursday.

After a roller-coaster 2012 season, Griffin is excited about the possibilities. He compared Pollard to former Titans safety Blaine Bishop, who also was known for his feistiness.

“He makes his presence known. Now we have a guy who at any given moment can excite the crowd. And it makes the tight ends and receivers think twice about coming in certain areas, and even running backs,” Griffin said. “Everyone knows what he is about. When the ball carrier gets to the second level, it can mess with your mind-set. He’s a great addition. The guy is a big hitter for sure.”

Pollard, who was nicknamed “The Bonecrusher” at Purdue, became the ninth free agent and second safety to join the Titans this offseason. Former Bills safety George Wilson agreed to a two-year deal last month. Then the Titans released veteran safety Jordan Babineaux.

The Titans hope the presence of Pollard and Wilson will help Griffin settle in and return to his Pro Bowl form of 2008 and 2010. Last season Griffin bounced between free safety and strong safety, but he’s usually played better at free safety, the position he prefers.
