PHILADELPHIA -- In football, it would be like assigning a linebacker to chip the opponent's tight end at the line of scrimmage, then having someone else right behind that linebacker to handle the actual pass coverage.
In basketball, it would be like assigning a forward to defend a guard outside the arc, then having someone else right behind that forward should the opponent still penetrate the paint.
It's a second wave of defense, basically.
If one were tempted to find a baseball parallel, it'd probably be a shortstop shading way over behind the third baseman.
In hockey ... well, I honestly wouldn't have been able to come up with a parallel of any kind until the Penguins, in particular Mike Sullivan and Jacques Martin, concocted a penalty-killing scheme unlike any I'd seen for their 5-1 victory over the Flyers in Game 3 of the Stanley Cup playoffs Sunday at Wells Fargo Center.

The punchline: The PK went 6 for 6 after struggling hugely for, what, two months now?
The explanation: See above, then paint any of those pictures onto a sheet of ice.
