Depends on when Bear is ready right?
But seriously, Myers is here still because of the reason you suggest, they just don't have anybody better. It's a question of availability and cap hit. Allvin said himself that Myers was going to play. Allvin also said that they like Juulson so likely they have Hronek, Myers and Juulson on the right barring some very fortunate circumstance.
Bear looked like a good fit but of course, they have to play the odds and based on his injury and likely rehab, they can't count on Baer even though they like him. Hard call but you have to like Allvin's pragmatism.
On the left, the have Hughes, Soucy and Cole which will be just fine.
Over all, the D is much better than last year
This is a short term solution and the D will be much better. They're going step-wise and that is ok by me. Next year will be another step.
