Single high as a base is a risky scheme to run when you have a corner that is struggling like Mo and a team that attacks seams like Garçon Moss and Robinson did against us.
The whole point is that Claiborne is better in man/bump-and-run coverage than when we use him in zone. He played a much better game against Denver and said afterward on the postgame show that the Cowboys played a lot more man coverage with the corners.
I'd rather put Claiborne, Carr and Scandrick out there on an island, with a safety slanting over to help in certain situations, than continue to play coverage where teams can just pick apart our linebackers and safeties with the tight ends and backs.
We paid a hefty price to get Claiborne and Carr, let's ask them to carry that load. Bracket the tight end (on most plays), man up on the running back (on most plays), and give over-the-top safety help to whichever corner needs it most or has the toughest matchup.
I'd rather have a team have to consistently beat one-on-one coverage by Carr, for instance, than beat one-on-one coverage by Church.
