You could argue that if management had more confidence in Perrault, the $3 million in Grabo money could have been used to get a stable partner for Green.
I'm not necessarily making that argument, because I like Grabo. But Matty P had pretty good success playing with Chimmer and Ward down the stretch last year.
All that said, the composition of that Ducks team is better for Matty P's game - the team is bigger and the players up and down the lineup play a more responsible and "harder" game. Perrault can do his water bug thing a bit more freely and aggressively, because there's more assurance that his mates will cover for him when a high-risk play goes awry. As a result, you play with more confidence - and that magnifies if your coach is showing confidence in you.
