I can't see Mancini or Willander being a #7 and spending extended stretches in the pressbox. Maybe they do some sort of 3 man rotation for 2 spots with the rookies, but makes more sense imo for 1 of them to be an Abby when the roster is healthy.
Hoping Forbort gets re-signed and he and Junior compete for the 3LD spot. Some sort of rotation to keep both in game shape while all 4 LHD are healthy.
Then Mancini and Willander ideally shuttle back and forth between the top pairing in Abby and the 3rd pairing in Van. Think it's better for both guys to be getting 22+ minutes in Abby than sitting for 5+ games in the pressbox. Even alternating games or whatnot would still mean they're missing 50% of the possible games played, which isn't ideal imo.
Not sure which RH guy will start where next season, but i do expect one to start in Aby but both to see a significant number of NHL games (assuming Willander hits the ground running as I expect).
The emergence of DPetey and Mancini, both of whom look very promising, really changes the outlook of everything.
