His time away from the game gave him perspective. Of course, family is always of utmost importance and the established routine he had while at home was helpful. He also grew an even bigger appreciation for his spot on an NHL roster.
"When you miss that for a while, you really want to get back," Letestu said.
Turns out, the Jets wanted him back just as much.
Letestu received the "all clear" from the Mayo Clinic in February.
"I think I was in on a Thursday, I asked if I could come back on Monday," Letestu said. "(Milette) said 'I want you back sooner. Can you be in on Saturday?' So it was a really cool feeling to be wanted and needed again, then get back in the group."
Under Milette's watchful eye, Letestu skated on his own in a track suit, then in a non-contact jersey with his teammates. By the time March rolled around, Letestu was close.
On March 10, Letestu was assigned to the Manitoba Moose on a conditioning assignment.
"That was an opportunity to see where I was at physically to go out with the Moose and play," said Letestu, who watched the Jets beat the Oilers on March 11.
"Then Rudy Gobert all of a sudden has tested positive (for Covid-19) and the NBA is shutting down," he said. "You could tell right then that the world was probably going to change, especially sports."
Letestu and the Moose had a flight at 6 a.m. CT the next morning to head to Milwaukee. They got on the plane, but got the news when they arrived that the season - and Letestu's comeback - was on hold.
"You land, then you hear that they're shutting things down. We stayed a couple hours, had a coffee in Milwaukee, and flew back," he said.
"That was disappointing for me… it's just one of those years. It wasn't going to happen."
Now back in Ohio with his family, Letestu calls himself a "full on baseball dad" as his kids are playing Little League baseball tournaments and he's going from ball diamond to ball diamond with them.
"I'm enjoying as much time as a I can with my kids and my wife. We have a bit of a moving target for when I'm coming back," he said. "There is obviously a focus on that and training and skating and being ready for Game 1 of the playoffs whenever that day comes."
