The penalty kill is absolutely ruining them.
They need to stop playing big slow guys like Antropov on the penalty kill, and instead focus on installing speed throughout the units. They also need to stop the passive box they tend to play.
Back in the mid to late 80's, the Jets had one of the top penalty kill units year after year. Doug Smail and Ron Wilson were speedy, agile forwards, who pressured the point at every opportunity.
Opposing defencemen could not handle the extra pressure, often sending wayward passes down low leading to turnovers, or losing the puck at the line, creating 2 on 1's and breakaways the other way.
The penalty kill became a weapon that often turned the tide of momentum in the Jets' favor. Right now, the penalty kill is an anchor.
Slater, Burmistrov, and Wright should be constants on the penalty kill. All of them are quick and agile. I'd also install one of Kane or Wheeler on the second unit (they can alternate) because the Jets are lacking another speedy defensive forward.
If the Jets switch from the passive box, to a more aggressive penalty kill based on speed and pressure, I believe they'll turn everything around in short order.
