The Colts got burned on four deep passes in Houston on Thursday night. Three of those passes were against man-to-man coverage. Pierre Desir got burned twice, and Rock Ya-Sin got burned once. These were all massive plays in the game.
They were all when the Colts tried to play man-to-man coverage. This defense is primary a Cover 2 zone defense. They excel the most when they keep the offense in front of them. That’s also what most of the secondary is built to do for this team.
When they got burned on those plays, they let a quarterback who doesn’t do well against zone coverage get exactly what he wanted.
