Well we both know those numbers don't actually mean "best", and that complementary players will get their value boosted in the right circumstance. The important part to note about Bunting is that his xgar was amazing even in a 3rd line role in Arizona.
I guess the question is this - are you projecting a significant decline from that line in either production or expected goal share? Even while noting that their multi-year xgar supports that level?
I understand why a model automatically regresses the elite performances but that doesn't mean it's actually likely.
