Jeremy Colliton had difficult shoes to fill. That's an understatement.
He replaced a three-time Stanley Cup winner and the second-winningest NHL coach of all-time in Joel Quenneville. And Colliton jumped in at the age of 33 just days after he and his wife welcomed their third child.
To make things even more complicated, Colliton took over as Blackhawks head coach just one month into the season and had to implement some new components of his system on the fly. That took a while for the veterans who had been playing one way for the last 10-plus years to adjust.
Colliton's No. 1 priority when he came to Chicago was to help fix a power-play unit that ranked third-worst during the 2017-18 campaign with a 16.0 percent success rate and 26th through the first 15 games of the 2018-19 season with a 14.0 percentage. It wasn't getting any better.
But from the day he got hired and on, the Blackhawks finished with the seventh-best power play (21.8 percent). It dried up down the stretch, but that was after a two-month span where it was converting at nearly a 40 percent clip. It was bound for regression.
The penalty kill, however, is something that stayed in the basement of the NHL all season long. They were 23rd under Quenneville through the first 15 games (76.6 percent) and finished last with a 71.7 percent kill rate under Colliton in the remaining 67 games. You can overcome a struggling power play, but it's almost impossible to overcome a bad penalty kill.
At 5-on-5 play under Quenneville this season, the Blackhawks had an expected goals for percentage of 45.8, a scoring chances for percentage of 49.2 and high-danger chances for percentage of 43.6, according to naturalstattrick.com. Under Colliton, they had an expected GF percentage of 45.8, SCF percentage of 46.9 and HDCF percentage of 42.6.
The sample sizes obviously aren't the same (15 games vs. 67) and, as we mentioned above, it took a couple of months for the Blackhawks to really get comfortable with Colliton's defensive structure. They certainly went through growing pains.
But with the Blackhawks expected to be active this summer in free agency and adding players that fit their new head coach's style, coupled with the fact that Colliton will have a full training camp to iron out the kinks and incorporate even more elements into his system, and the team could hit the ground running for the 2019-20 campaign rather than playing catch-up all season long.
"I think as you go you get more comfortable, you gain confidence, you go through experiences and deal with situations that come up and they're challenging at times," Colliton said. "You get through it. And then the next time stuff comes up, you feel more confident, you feel better about what you're doing. I had confidence when I came in November that I had a plan and we as a staff could make some progress. It took longer than we all would have liked, but I think I'm a better coach now than when I walked in, and I'm going to use that going forward.
"There's going to be challenging circumstances next year too where maybe doesn't come easy. But I think all the best coaches get better all the time. Every day they're bringing new ideas and new energy and looking outside for inspiration. That's what I expect to."
