Here's a frame-by-frame analysis of the O-line performance, including the blocking by TE's. For all the tools who love to point fingers at FWP for putting us in third and long, just look at the plays. As you can see, there are multiple occasions of the D-line getting into the backfield before the RB even makes it to the LoS. I sincerely hope that Hartwig is an upgrade and the line 'gels' before the season. If they don't, we could be seeing more of this.
And yet, I'm willing to bet FWP will still take the fall for every third and long we come across.
