I like what Boston did last year in the playoffs tbh.
Swayman started game 1 and was lights out.
But even then, they started Ullmark game 2, just like they had alternated all year long, and Ullmark was ok but not great.
Swayman started the next game and was awesome again.
And then they just went with Swayman.
Until he gave up 4 goals in 2 periods in gm 2 of rnd 2, and they yanked him.....but Ullmark came in and gave up 2 quick goals anyways.
The toughest call then was for game 3 - which they gave to Swayman despite his 1 bad game......and Swayman shat the bed again, giving up 5 goals. I don't know that Ullmark would have been the better choice that game, but that game may have decided the series. Swayman started the last 3 games and was good in all of them, but it wasn't enough.
