The Singleback Bunch Curls play is very effective against cover 3 and man free (cover 1) coverages. It's designed to horizontally stretch the curl/flat defender by forcing him to make a decision on which defender to cover. If the curl/flat defender (usually safety or outside linebacker) runs to the flat to cover the flat receiver, this opens a passing lane for the quarterback to throw the curl route to either outside receiver. If the curl/flat defender sinks in coverage in an effort to take away the curl route, the quarterback can then go to his receiver running the flat route.
nice.
