Good read. However, he's just guessing like we are. For example, he blames Demps for this
Which is possible. However, with 4 guys on the right side of the defense & the middle void of any Texans player, I would bet one of those LBs was supposed to drop to the middle. It looks like one LB has pretty good "man" coverage on a TE (maybe). My guess would be that he should have dropped (since that is where Quin came from) & that TE was should have been released to the other LB already on that side. Also being the LBs were just thrown into this game, I can easily understand blown responsibilities by this group.
I'm glad that he recognized the lack of pass rush as the biggest problem. But showing stills of one on one plays don't tell the whole story.
