Grizz is too small for 7 game series and Ullmark costs too much. Swayman and Bussi are the future. Plus Ullmark’s GAA is near 3 and save percentage is approach .900
Bruins could use another solid C in Couture. Poitras is great but won’t cut it yet in a physical 7 games series (needs to fill out still). Blackwood is NHL tested and can fill in if Swayman is injured. Its a gamble but my guess is any NHL goalie would do substantially better in front of Bs team D
