playing the flats in robber coverage

assuming it is a "quick" out, whoever has the flats in your zone would have primary responsibility (your spurs, probably). Corner can not take it because he has deep half, and your robber (FS) is playing underneath. It should be your spur on this. Yes, it can be a tough job against a very good receiver and a QB with a good arm, but still his responsibility.

For us our spur has flats and is lined up over #1 with the corner over #2. Your spur has the flats and if not threatened in his zone continues to stink. Once #2 makes his move to the out the spur comes up and the corner has the deep WR. We look Cv3 but are really Cv2

Coach yes he would. Our spur doesn't line up in a 9 tech. He his 4x4 off the last man, I may look at going 3x6 this year to take away quick passes but I have to look at first. Like I said our spurs have the flat they are not responsible for over the top as the corner and safety will be on any double verts

I don't so. With the Spurs like this he sees the off tackle play coming right at him. This allows him to step up and squeeze the play back inside to where the LB's/Dline are. As for the FS He will almost always play hi normal alignment, but if we were to play a team who liked to hit the TE then we might look at it
