"They had asked if we might be able to send him a stick to maybe cheer him up [after the surgery]," Zucker said. "My wife, being the woman that she is, said 'No, we're going to bring it to him, we're not just going to drop it off.' So we chose a day where we didn't have a game and went in and saw Tucker, and it was the most fun I've ever had."
Zucker and Helstrom chatted for hours while playing NHL video games. Helstrom even offered coaching advice to Zucker, telling him to backcheck hard and shoot more; that last piece of advice will stay with Zucker forever.
Zucker and his wife, Carly, visited Helstrom before almost every round of chemotherapy, and before they headed to their offseason home in Las Vegas this summer.
On June 29, Zucker signed a two-year contract with Minnesota. What should have been a celebratory time quickly took a turn. Helstrom's cancer had spread to his brain. He didn't have much time left. Zucker was on the next flight to Minnesota. He landed at 5 a.m. on June 30 and was with Helstrom that afternoon.
"It was the first time I realized that something was really wrong," Zucker said. "We obviously knew that cancer was something awful, of course, but that was the first time you really tell what this disease had done to Tucker.
"It was very hard for Carly and I to see Tucker like that because he was such a strong kid. Every time we saw him he was so strong. He was 9 years old and he was battling through it, and he was doing an incredible job, but for the first time you could see it was hard."
Helstrom died three days later.
In addition to the tattoo, Zucker is remembering Helstrom with Team Tucker's Locker, a section located in Kyle Rudolph's End Zone -- named for the Minnesota Vikings tight end -- at University of Minnesota Masonic Children's Hospital. The room serves as an escape for kids at the hospital, complete with games and movies. Team Tucker's Locker corner will mimic a stall in the Wild's locker room with a Team Tucker nameplate and jersey.
"Kyle brings the football aspect and we're bringing the hockey aspect," Zucker said. "It'll be a fun way for the kids to go have fun and just be kids."
