Analyzing Super Bowl XLV: Where Are Green Bay's DBs Vulnerable?

The last time the Steelers and Packers played, the two teams combined for nearly 900 yards of passing offense and six passing touchdowns.

Considering the quality of the Steelers and Packers defenses this year, it's hard to imagine we'll see a similar airshow on Sunday. This year, the two secondaries finished first and second, respectively, in quarterback rating allowed and third and fourth in the league in passing touchdowns allowed.

But to get a better sense of where these two teams may be vulnerable, here's a look at each and every passing touchdown the Packers allowed this year. A similar breakdown of the Steelers is here.

TOUCHDOWNS ALLOWED
Tramon Williams	3.5
Charles Woodson	3.5
Sam Shields	3
Unable to be determined	2
Nick Collins	1.5
Charlie Peprah	1
Brandon Chillar	1
Morgan Burnett	1
Nick Barnett	0.5
A.J. Hawk	0.5
Jarrrett Bush	0.5

A couple of things jumped out when watching the touchdowns. For one, it was a great reminder of how many injuries the Packers have had this year. Brandon Chillar, Nick Barnett and Morgan Burnett may be on this list, but they are not on the active roster now because of injuries.

The other, and more significant observation, was that the Packers are more vulnerable to tight ends over the middle than receivers hugging the sideline. That may be in part because while the Packers have excellent speed on the outside, their safeties are not as strong, especially at strong safety with Charlie Peprah.

Seven of the 19 touchdowns the Packers have allowed this year have been to tight ends. Two of those came when teams timed tight-end screens perfectly -- running them to the side that the Packers' blitzed from. In both Antthony Fasano catch and run in Week 7 and Will Heller's similar play in Week 12, the tight end had an easy time after simply turning around and catching a short pass--there were way more blockers in front of them than defenders.

But Green Bay also seemed to have matchup troubles in the red zone with tight ends, Greg Olsen, Tony Gonzales and Aaron Hernandez's touchdowns all came on simple routes in the red zone where they could use their agility and big bodies to either find holes in the zone or simply outfox a Packers' defender.

Green Bay's other weakness would appear to be tackling after the catch. Since Week 11, the Packers have given up three touchdowns of 30+ yards where a defender had a chance to make the tackle, failed to make it and the receiver/tight end then ran the remaining 20+ yards.
