Josiah is following a nearly identical path as his older brother, Jaccob, a defenseman for the Carolina Hurricanes.
Jaccob, four and a half years Josiah's elder, was drafted by the Carolina Hurricanes while playing with the USHL's Chicago Steel. He spent two years at Colorado College before signing his first pro contract. Jaccob played in 14 AHL games his rookie season and has been an NHL regular ever since, already surpassing the 400-game mark in just his sixth season.
Josiah was drafted in the seventh round by Chicago in 2018 and then spent the last half of his final junior season in 2018-19 with the Steel, appearing in 27 games while scoring 20 points (14G, 6A). He, too, spent two years at Colorado College before signing as a pro, amassing 26 points (10G, 16A) in 56 games with identical 5-8-13 stat lines each season with nearly a third less games the second time around.
"It's awesome that he kind of set the way for me and developed the path through the college hockey route," Josiah said. "I kind of wanted to follow in similar footsteps. It took me an extra year to do it since I aged out of juniors, but we're here now and I couldn't be more excited about it."
The big brother had sound advice for the younger Slavin sibling as he enters the next chapter of his career.
"He just told me to trust in myself as a player," Josiah said. "He thinks I'm ready for the next level and I've got to believe in myself to know that I'm ready for it too. And just to enjoy the moment. You only sign your entry-level contract once."
