Stumbled across a website headline asking the question "Is a free agent familiar to coach Mike Zimmer a good fit for Vikings?"

Experience tells me, "Um, duh."

Best example I can think of: Early 1990s, Cleveland Browns. A fella named Belichick showed up in Berea, Ohio with a system in mind and ideas for how to begin implementing it. He wasn't the eccentric genius he is today. In fact, he wasn't even 40 years old and he had never been a head coach before.

Even with his two Super Bowl rings as Bill Parcells' defensive coordinator with the Giants, the leftover players didn't care for this cold-hearted, mumbling, monotone man who would walk by them in the hallway and not even make eye contact. Two players -- Michael Dean Perry and Reggie Langhorne -- even walked off the practice field after clashes with Belichick.

It wasn't long before Belichick turned to the east and began Pied Pipering a line of former Giants to Cleveland. Joe Morris, Pepper Johnson, Carl Banks, Everson Walls, Mark Bavaro were among the loyal Belichickians who arrrived with some gas still left in the tanks. We used to ask Belichick when LT's -- the original LT (Lawrence Taylor) -- flight would arrive.

Even Phil Simms was so close to signing that the Browns actually called a press conference to introduce him. With reporters and TV cameras waiting in the interview room, last-minute talks broke down. After a lengthy delay, an introductory presser suddenly became a hurry-to-the-parking-lot-to-ask-Phil-what-the-heck-happened news scramble.

That's the long way of saying, yes, Zimmer will have interest in "his guys" from Cincinnati. It's only natural. No, his guys didn't win a couple of Super Bowls like Belichick's guys did over 20 years ago. But the Bengals sure have known how to play some solid defense under Zimmer.

Here are the Bengals to keep an eye on:

DE Michael Johnson: The unrestricted free agent who makes the most sense for the Vikings. He's 27, 6-7, 260 and has the skills to rush the passer but the dedication to play the run even if doing so results in fewer sacks. That last part ain't easy for right defensive ends to swallow. Jared Allen isn't coming back, folks. He'll be 32 and there are better teams who need pass rushers and will pay dearly for them. And, frankly, he doesn't fit the Vikings' new defense. In Zimmer's seven seasons as Bengals defensive coordinator, only two players -- DT Geno Atkins and Johnson -- have had double-digit sack seasons. Johnson had 11 1/2 in 2012. He had 3 1/2 last year, but, according to ESPN, he tied for first on the team in pass disruptions. And the Bengals were fourth as a team in that category.

MLB Vincent Rey: Remember him? His pick-six against Matt Cassel in Week 16 gave the Bengals a 21-7 lead early in the second quarter, sparked the onslaught and essentially was the final boot the backside of Leslie Frazier's career as Vikings coach. Rey is a 26-year-old restricted free agent. But the Bengals put the lowest tender -- $1.431 million -- on him. That means the compensation is a pick in the round he was drafted. And since he was undrafted, there is no compensation in terms of draft picks. The Vikings need playmakers at linebacker. Rey knowing the defense would be a big advantage.

Other Bengals to watch: S Taylor Mays, 26; CB Brandon Ghee, 26; S Chris Crocker, 33. Yes, Crocker is an old player. But he's a big-time Zim guy. He came out of retirement the past two years when Zimmer needed help at the position. "I did it because I still felt I could play and because of Mike Zimmer," Crocker said during a phone interview shortly after Zimmer was hired by the Vikings. Asked if he'd be willing to come back a third time, Crocker laughed. "We'll see," he said. Crocker doesn't fit what the Vikings typically look for in free agency. But, hey, he's tight with the head coach and he believes in the system.

Zimmer's thoughts: Zimmer was asked by reporters on Thursday about how hard he'd be chasing after his Cincy guys. He said: "It always helps because of the communication, but it's not relative. I had no one in Cincinnati [his first year]. Matter of fact, I was the only new coach I think when I went there on defense. I had no players that came with me at that time. It'd be nice, but it's not imperative."
