All of this Couturier at 1C talk...
I think people are getting a bit overexcited after an unsustainable stretch of play to finish the year.
Yes yes yes yes yes yes I know he had the most 5v5 points on the team, but 17 of those came in the last 20 games.
In his previous 46 games, he had 14. Which is 0.304 5v5 points per game, a lower scoring rate than the worst 5v5 player to ever play in the NHL (Giroux, or at least I assume he's the worst, based on the complaints on here), who had 0.306 5v5 points per game in the same time period (which is also a larger sample size because he played 62 games). Obviously that's a tiny difference, but the point is that without that unsustainable play Couturier is no better than people who are CONSTANTLY *****ed about because of their 5v5 play. That time period also includes Giroux's horrendous stretch of play from Xmas until March 1st, where he had 3 5v5 points in 26 games, an outlier that seriously lowers his 5v5 ppg pace.
Plus, lets remember Giroux is getting matched against the opponents best defensive players. Couturier has hard usage, from a defensive standpoint, since he's playing against opponents top scorers, but most of those guys aren't exactly above average defensively. Easier to get scored on, but also easier to score against. If we're using Couturier as 1C with Giroux on his wing, he's going to get used against opponents best defensive players, so likely less scoring, and he's also not going to be going up against the opponents best offensive players so we'll probably get scored on more (obviously whoever replaces him as the person expected to shut down opponents won't be nearly as effective).
So, while in theory that line might sound nice, I seriously doubt it would work out well. It'd probably be better to let Giroux stay at 1C, hope he bounces back to how he was up until Xmas and the previous season. Then, if he doesn't, maybe the following year put Hischier or Patrick in that spot (if they look like they can handle it), with Giroux on their wing. Couturier stays in his current spot, both shutting down opponents top players and taking advantage of their lacking defense once in a while.
