Philadelphia Eagles (99.9 percent)
Playoff kryptonite: Offensive tackle Halapoulivaati Vaitai
This exercise is virtually futile for the Eagles, who are the most balanced team in football and don't appear to have an obvious weakness. They rank in the top eight in both passing and rushing offense and defense DVOA and are 10th on special teams. They're fourth in DVOA at defending short passes and long passes. They run efficiently and generate big plays. They rarely turn over the ball, and they force plenty of giveaways.
To be fair, Vaitai has looked better in this second season as a regular filling in for a missing star on the Philadelphia offensive line. Vaitai was posting up at right tackle for the suspended Lane Johnson in 2016; this season, he's lining up at left tackle for the injured Jason Peters.
On Sunday night, though, we saw what might happen when Vaitai goes up against upper-echelon pass-rushers. Seahawks end Frank Clark beat Vaitai for two sacks, and MVP candidate Carson Wentz spent much of his night running away from pressure on his blind side.
Plenty of teams will place their star pass-rusher on the left side of the field and go after what is generally a weaker pass-protector at right tackle, but Vaitai could encounter a few stars as the Eagles push toward the Super Bowl. Clark could come in for another appearance, but I'd be particularly concerned about someone else. Everson Griffen has been an absolute terror for the Vikings this season, and 11 of his 12 sacks have come as a right defensive end against an opposing left tackle. The Vikings also can rotate Danielle Hunter and Brian Robison into the lineup when Griffen takes a play off, which means no breaks for Vaitai. The Eagles will give him help, but against dominant pass-rushers like Griffen, help might not be enough.
