The enjoyment has translated well for Tomasino, who is No. 24 in NHL Central Scouting's midterm ranking of North American skaters eligible for the 2019 NHL Draft in Vancouver, on June 21-22.
Some of Thomas' advice, however, has been to ignore outside noise, including draft rankings.
"There's a bunch of rankings that come out and obviously you want to be as high as possible and a lot of different people have a lot of different perspectives and opinions," Thomas said. "There's a lot of things that don't really matter. And for a guy like me, I'd kind of get upset to the point where I had to lay off Twitter … I actually deleted it for a bit.
"The best way to deal with it is to not even deal with that stuff. He's doing a pretty good job with that."
Thomas is proud of how Tomasino has rebounded and played some of his best hockey as Niagara is getting ready for the playoffs, with nine points (five goals, four assists) in his past six games.
"He's been a lot more confident," Thomas said. "That's what I've seen the most. Now when he gets the puck he attacks the defenders and he has it in his mind that he's going to dominate the game. I think that is kind of the first time we've seen it. He's only a second-year guy.
"Last year he had a good year (24 points in 61 games), but everyone's first year is tough. Now I think he feels like he can dominate this league rather than just fit in. It's been evident. He's been scoring game-winning goals and big goals. He's been scoring a lot and really confident. It's really cool to see."
That success has helped alleviate some of the pressure Tomasino was feeling.
"Having more confidence, I think, knowing you can play with these guys and being a difference-maker, helps," he said. "The nerves got away from me and I kind of stopped focusing on the draft and focused on my game and it ended up working in my favor. It's been great."
