Is that so he's able to expose his 4M for the expansion and meet the 25% rule?
Seids is now a slow overpaid #5 who is great on the PK. Bruins will improve when they'll be able to spend his 4M more adequatly.
Only one of Seids, McQuaid, K. Miller should be back next year. I'm keeping Seids to help with the expansion draft. Cap should not be a problem this offseason even with Seidenberg. Next year is different as Marchand, Spooner, and Pastrnak need new contracts.
