Quinn didn't really say all that much. Just that they need to do better essentially.
It seems they need to ratchet up the intensity a bit and fill the freaking gaps. It seems our guys are waiting to be blocked and then letting it wash them out of the plays too easily. Seems Tree is the worst about this. The intensity will be there for Seattle, I'm sure. But I sure would like to see some of it Saturday.
Just adding to your comment:
I saw a lot of them, not being on the same page. Usually, each guy is responsible for a gap, zone, or area, like outside containment. If a guy like Donald, decides to rush up-field on every play, thinking the play is pass, he may vacate his gap entirely, leaving a hole too large for the LBers' or Safeties to fill. Tree, or JL, may see too many gaps to fill, and wait, causing them to get washed out. Trusting your other players to OWN their responsibilities, will allow us to play faster, and better.
The offense's goal, sometimes, is to give you false reads, hoping to confuse, or suck you into an area, counter to where the play is actually happening. A good runner with vision, and ability, can screw the whole plan, on both sides. Either way, we have to beat each individual, to each spot. Trust your teammate, do your job, then have their back, in that order.
