I believe Canada is making 16 cuts after today's scrimmage. Holloway obviously won't be one of them as he hasn't even had a chance to play yet. That would put them at around 16 forwards, and I expect them to take 13-14 with them to the WJC. That means that as long as Holloway isn't among the last 2 or 3 cuts, he's almost guaranteed to make the team.
These scrimmages don't have as much of an impact as some think. Team Canada's coaching staff came into the camp with a very good idea of what their team was going to look like. And the fact that they brought in Holloway despite the quarantine period and the knowledge that he would miss the team's opening scrimmages means there's a good chance they've seen him as a lock right from the start.
I think you might be surprised at who Holloway will make the team over. Craig Button said that there are a group of 02s that are essentially here to prepare for next year's tournament and were never really in consideration to make the team. He mentioned names including Cole Perfetti and Seth Jarvis. I'm not saying I agree with those players not making the team — because I don't — but it seems like Team Canada will go for role players rather than purely offensive talent. I expect Holloway to make the team over some big names and play an important role in the bottom-6 and on special teams.
