In my recent linebacker review, I evaluated all the youngsters with a fairly skeptical eye. However, in discerning some difference between their various deficiencies, I noted what now seems to be patently false.

I said, “Brian Rolle is the opposite of Chaney, smaller but smarter and a better tackler to boot.” Well, the last part just isn’t true, according to the statistics provided by Pro Football Focus. Derek Sarley alerted me to this article by PFF from a year ago.

The stat they come up with is Total Attempts (sacks, tackles, assists, and missed tackles) per Missed Tackle. From 2008 to 2010, the top 15 linebackers in the NFL had more 20 or more attempts for every miss. Meanwhile, the bottom 15 qualifying linebackers registered fewer than 8.8 attempts per miss. Here are the numbers for returning Eagles:

The thing that should stick out to you is Rolle’s atrocious number. According to PFF’s charters, he had a missed tackle once every five times he had the chance. None of the linebackers really have good results here, but Rolle’s is by far the worst. If he had qualified for PFF’s study last year, he would have been the single worst LB tackler in the league.

I was never that high on Rolle, given his limited upside. But apparently my eyes deceived me about his tackling. If he’s both small and a poor tackler, that makes him a real liability, and an underdog to retain his starting weakside role.

Chaney, Casey Matthews, and Moise Fokou were all pretty poor tacklers last year as well, and in truth their numbers above may actually underestimate the problem. At the risk of relying on my memory of last season again, Chaney’s problem was often that he failed to even get to the ball. That poor diagnosis and reaction wouldn’t factor in to this statistic, which just counts actual tackling attempts.

Still, we might be able to count on at least one of the youngsters to improve in 2012. Want a scarier statistic? Over the last three seasons, DeMeco “Savior” Ryans has a 9.3 attempts/missed tackle ratio. That’s no better than Chaney or Matthews.
