I don’t see this at all. But I don’t think he was a bad move to take him out.
I see the series this way. Forbort had the misfortune of playing in the three games where the Bs really thought they could skate, forecheck, and play back and forth hockey. After all, easy Bs win game 1. But games 2 and 3, that wasn’t cutting it.
So, much tighter game 3. Bs blow a 2 goal lead, but realize they sort of need to go into a shell, hang back, Fs way back more so, etc. It lead to more team overall D coverage with the offense completely drying up. But hey, at least they were in these low scoring games and had a chance. They had a hot goalie and thought they could ride it out. Bringing Peeke in for game 3 really added nothing. And maybe Wotherspoon should not have sat.
Games 4, 5, and 6 were all played passively by the Bs. ALL the players realized by then they needed to play a much tighter game and hope for the best. It didn’t work out.
In the end, Forbort was 1-2 in three games. Peeke was 1-3 in four games. Wotherspoon was 2-3 in five games.
So, no. The series would not have turned out any different because Forbort played a few games.
