BEREA, Ohio -- When Eric Mangini first arrived in January and studied the Cleveland Browns' game tapes of 2008, there wasn't much that stood out from their 4-12 season. That was evident after the new coach swiftly executed an immense roster overhaul in his first offseason.
But there was one player who caught Mangini's eye in nearly every game he studied: Browns linebacker D'Qwell Jackson.
Mangini watched Jackson hustle. He saw Jackson flow to the football and make play after play, despite the fact most games were out of reach and playoff dreams were shattered by midseason.
The result for Jackson was an NFL-leading 154 tackles in Cleveland's No. 26-rated defense. His accomplishments last season went mostly unnoticed except in the film room of his new head coach.
"I've really enjoyed watching D'Qwell," Mangini said. "He is pretty much in the frame at the end of every play and that is always what you look for. You always try to count how many defenders are in that last frame and he seems to be everywhere."
Jackson is happy someone recognized his play last season and plans to use it as motivation.
"It's a great compliment coming from the head guy coming in," Jackson said. "Now I got to take it and run. I don't call it pressure but it's my job to fulfill that role. I have to take a bigger leadership role and I have to be the guy to count on these plays."
The Browns are a combined 5-19 against the Ravens and Steelers since 2003, because those two teams physically dominate the Browns at the line of scrimmage. The Cincinnati Bengals split with Cleveland last season but are also making significant improvements this offseason to become a more physical team, following the blueprints provided by Pittsburgh and Baltimore in the division.
Even with Jackson's production, Cleveland was very pedestrian defensively. The Browns failed to stop the run (rated No. 28) in 2008 and couldn't sack the quarterback, posting an anemic 17 sacks in 16 games.
As a point of reference, Steelers outside linebacker James Harrison had 16 sacks alone in 2008.
"If you look at that defense, he's certainly not the problem," Matt Williamson of Scouts Inc. said of Jackson. "If there are 11 starters, he's probably the second- or third-best guy. [Defensive tackle] Shaun Rogers is their best player on defense, and D'Qwell could very well be their second-best player."
Critics of Jackson often say too many of his 154 tackles were not impact plays. Williamson agrees to some extent but added that one player cannot stop the run alone. It takes all 11 defenders shooting their gaps and knowing their assignments, which has been a challenge for Cleveland in recent years.
"D'Qwell does tend to make a fair amount of his tackles further down the field than you would like, but he is still a very good player," Williamson said. "He's a very good tackler, has good reaction, and he doesn't take many false steps. He's also good in coverage, so there is a lot to like there."
For Jackson to take his game to the next level, the former second-round pick in 2006 will need a lot more help running Mangini's 3-4 defense. Cleveland's coach acquired assistance in the form of several defenders Mangini worked with in his previous stint with the New York Jets.
Veteran starting linebackers Eric Barton and David Bowens, both older than 30, will work closely with Jackson. The Browns also added former Jets at every other level of the defense with safety Abram Elam and cornerback Hank Poteat helping in the secondary and C.J. Mosley adding depth on the defensive line.
But Barton in particular has been a great tutor for Jackson, because Barton will line up next to his younger counterpart at middle linebacker. The two former Maryland Terrapins, seven years apart in terms of experience, are expected to become the leaders of Cleveland's defense and are already developing a good chemistry together.
"All of his career he is a Mangini guy, and you know Mangini i
s a smart guy," Jackson said. "That's what Eric Barton stands for; that's what type of guy he is."
From the second Cleveland's new coach turned on the game film, Jackson showed potential to become the latest "Mangini guy." Now it's up to Jackson to prove on the field in 2009 that he deserves that distinct moniker from his new head coach.
