We know Schenn is a good enough 2C to win a cup. Why are we trying to get Buchnevich there? Just let Schenn stay 2C for ever. He won a cup once as 2C. He is the only #2C we have ever had do that. </sarcasm> Yes, I am being sarcastic here. But its been 5 years, let's judge players for who they are now.
Things change. Binner has never repeated the #s he put up in 2019. He's had down-right bad years. Although he appears to have his head on straight now, he is aging. And our core is younger than he is. Its going to be a few years until we can compete. Will he be as good in 3 years? Instead we could get a younger goalie whose age matches our core who would be signed long term with a rising cap. If the price is right, its a no brainier to swap the two if we can for me and I generally do not like paying a ton for a goalie.
*As always, when discussing Binnington, I note for transparency that I do not like him as a person, and that may effect may discussion of him as a player.
