Defensive line making offensive line look offensive

So far so good for the Vikes D line and they continue to run round and round the O line. Center John Sullivan appears to be holding his own, but the rest of the guys look like turnstiles. The real issues is Left tackle, where Matt Khalil is absolutely smokes by Everson Griffith on almost every play. Granted, Griff had 12 sacks last year and looks like the real deal, but Khalil needs to step it up, as he will be going against every teams most talented pass rusher all year long. Good news for the Vikings is they do have 1 hope, 1 solution to this confounding issue; Adrian Peterson.
