Two of the bigs things I haven't heard much about are how good or bad their o-line is and how penalized they are. If we can draw some penalties on their offense, it will make sustaining long drives more difficult. So hopefully the stadium gets pretty loud, but I'd also bet you see some stunting and slanting from our d-line to try and draw some holding penalties even if they don't get to the QB.
I think the more important of the two is how good their o-line is. If our d-line can shut down the run with just the four down lineman, it could let our LBs and Rover drop into underneath coverage to shut down some of the shorter routes. I bet we'll see a lot of the looks where all the linebackers are at the line before the snap to try to confuse their QB and not let him know how many are dropping into coverage.
Overall I am pretty worried about this game, but I've also been worried about every game this year and our defense has found a way to limit teams, so I'm going to trust that Elko has a good strategy for this game.
