It's funny because the stats indicate that Toews performs almost identically with or without Makar on his pairing. This season and last season combined, Toews posts almost identical cf, sf, xg, etc rates with or without Makar.
I get you want Chabot on the team, and he'd be a fair choice, but I don't think you need to pretend Toews is some kind of passenger to Makar's brilliance.
I'd go so far as to say if Toews and Makar both make Team Canada, Toews will have the higher TOI. He's a player coaches absolutely love.
