Posluszny, Dansby won't give them a break

Earlier, I mentioned defensive coordinator Mike Nolan is a Miami Dolphins addition who often gets overlooked when judging their offseason.

Then Football Outsiders editor in chief Aaron Schatz produced a piece for ESPN Insider that reminded me about addition by subtraction.

The Dolphins' defense should be substantially better simply because linebacker Akin Ayodele and safety Gibril Wilson aren't on it anymore.

Schatz compiled data on the defenders who allowed the most broken tackles, defining them this way:

Either the ball carrier escapes from the grasp of the defender, or the defender is in good position for a tackle but the ball carrier jukes him out of his shoes. If the ball carrier sped by a slow defender who dived and missed, that didn't count as a broken tackle.

Ayodele was the worst among all linebackers, with 17 percent of his attempted tackles ending up broken. Wilson surprisingly didn't make the top 10 among defensive backs, but former Dolphins Andre Goodman (third at 20 percent) and Renaldo Hill (10th at 17 percent) were there.

Elsewhere in the AFC East, Bills linebacker Paul Posluszny and new Dolphins linebacker Karlos Dansby tied for sixth among the most efficient tacklers at their position, getting their tackles broken a mere 3.3 percent of the time last year.

In the secondary, Dolphins backup Jason Allen rated tops with no broken tackles, while safety Dolphins safety Yeremiah Bell was sixth best at 3.7 percent.

Schatz shared the team data, breaking it down both offensively and defensively at FootballOutsiders.com.

On offense, the New England Patriots were tied for fifth, breaking tackles on 6.3 percent of their plays. The Bills were tied for eighth at 6.2 percent. The Dolphins were tied for 15th at 5.6 percent. You'd think a run-dominant team like the New York Jets would be higher than 24th, making opponents miss on 4.9 percent of their plays.

Defensively, the Jets were the most efficient AFC East club, with opponents breaking tackles on 5.2 percent of their plays.

The rest of the division was below average. The Dolphins were tied for 18th at 6.1 percent. The Patriots were 22nd at 6.2 percent. The Bills were tied for 24th at 6.7 percent.
