PLD has affected matchups greatly. There is a reason the scoring is so spread out between lines, it's because it's a pick-your-poison. That's led to being a full goal per game ahead of last year so far.
Byfield is playing great, but he doesn't require a solid defensive guy in response, especially at center. His current effectiveness is tied to using speed to pursue and retrieve down the boards which will go away if he's at center and is coming up from deeper in the zone. Fiala isn't good at that and Vilardi doesn't have the speed, so it's a much easier matchup to deal with, force a dump and chip it out. Byfield isn't there yet with regards to carrying it in the zone.
It does look lateral more or less by production, but the effect of having 3 solid, experienced centers can't be overstated.
