The St. Louis Rams' first move in free agency was reuniting Fisher, who coached Finnegan for five seasons in Tennessee, with the feisty, productive cornerback. Fisher agreed to terms Wednesday on a five-year, $50 million contract with $27 million guaranteed and $33 million coming in the first three seasons.
With incentives, Finnegan could make another $1 million in incentives over the life of the contract.
"His reputation is widely misunderstood out there from the standpoint of, you know, the dirty player type thing and all that," Fisher said at a news conference Wednesday. "He's just a very productive player.
"He plays with an edge - yeah, he does. He challenges and he competes and he finishes every down."
The 28-year-old Finnegan had played all six NFL seasons with the Titans. He was undergoing a physical and Fisher planned a news conference Thursday morning to introduce the player. Finnegan just completed a four-year, $16.8 million contract and turned down several other opportunities to visit teams because of his respect for Fisher.
"We are recruiting Jason right now," Fisher said. "We hope to have a chance to get things worked out."
Finnegan was an All-Pro in 2008 and is known for his physical style.
He got into a punching match with Texans star wide receiver Andre Johnson during a game in 2010 - both were fined $25,000 - and had at least two other incidents that season. He was fined $5,000 for throwing Giants wide receiver Steve Smith to the ground and fined $10,000 for hitting Denver guard Chris Kuper after the player had taken off his helmet.
At one point that season, Finnegan said he wanted to be known as the dirtiest player in the NFL. Later that season, he claimed he was just joking.
Finnegan also walked out of training camp in 2008 during negotiations for a contract extension, apologizing the next day.
The Titans drafted Finnegan in the seventh round in 2006 out of tiny Samford in Birmingham, Ala. He's been very durable, missing just three games the last five seasons since becoming a starter. He had five interceptions in both 2008 and '09.
St. Louis is 10-38 the last three seasons, costing coach Steve Spagnuolo and general manager Billy Devaney their jobs. Along with the 30-year-old Bartell, defensive end James Hall (35), defensive tackles Fred Robbins (34) and Justin Bannan (32), and center Jason Brown (28) have been cut.
"We didn't sit down and say, `Hey, let's go get all the Titan and Falcon players we possibly can,"' Fisher said, referring to general manager Les Snead's former position in Atlanta. "It just so happened that two of the top guys on our list were my former players.
"It's just about getting the right people."
The most pressing need for the Rams going forward is probably finding a wide receiver to complement their investment in quarterback Sam Bradford, the top pick of the 2010 draft. Danny Amendola is healthy after missing virtually all of last season with an elbow injury, but free agent Brandon Lloyd, who added a spark last season, is unlikely to return.
"It's a position that we're going to address and we'll continue to address, and we'll fill the need," Fisher said.
Fisher said he had no timetable for when the NFL might rule on defensive coordinator Gregg Williams' bounty scandal. Fisher said Williams was "totally involved with everything" while awaiting what's expected to be at least a heavy fine and suspension.
