Michael Frolik and Marcus Kruger may not have envisioned the penalty kill being such a big part of their repertoire. Frolik, certainly not, considering he was a 20-plus goal scorer in Florida and had never played on the kill before the Chicago Blackhawks acquired him in a trade.

But it was nevertheless an opportunity. And whether it’s been the kill or their roles on the fourth line that gets a good chunk of playing time, Frolik and Kruger have been making the most of those opportunities.

“They’ve been real solid all year,” coach Joel Quenneville said of the two. “When they started at the beginning of the year it was a work in progress, and they’ve progressed in a real nice way. They’re first and third on each kill, they’re blocking shots, they’re getting in lanes and play at a good pace. It’s gotten them more of a role, more ice time. And that line played well all year, so a real nice fit for us.”

Here’s the thing about opportunity: When you get it, you have to latch onto it, embrace it and perform at the highest level on it. These two have done that. Their work on the penalty kill has kept them vital parts of it, and their solid fourth-line play has given Quenneville the confidence to put them out there in any situation.
