I'd take Raycroft. He blanked the Stars (not an easy feat) and he only gave up one goal to TB. Potvin is decent, but posts a .894 SV% and this number has decreased in the last 3 years, while his GAA has increased constantly over the last 4 years. Raycroft is the future of the Bruins. He's had improving numbers going from 2.96 GAA in 2000 to an impressive 1.43 GAA this year, and going from .890% in 2000 to .948 SV% this year.

You still gotta go with Potvin for now, if you are aiming for the playoffs you go with a more sure thing. Reevaluate at midseason to see if a change needs to be made.
