Borsig was probably right: you are an irritant. Nevertheless, I'll play along.
Assume the canes acquire Guentzel for let's say 2024 1st rounder, Jackson Blake; and one of Ponomarev or Ryan Suzuki. Heck, lets add a 2025 2nd rounder in. explain why this deal is terrible? do you really believe the Canes will be weaker without these assets, when odds are that none of these are on the roster next year.
when evaluating this, consider the value of Guentzel as: proven playoff performer and 2x champion; legit goal scorer; and improves scoring depth by pushing a winger down the lineup.
Bottom line is no one in the hockey universe , except you, would criticize the Canes for swinging big for Guentzel. multiple hockey pundits feel he is a really good fit for this team. I agree. However and this is big, the only opinion that matters is Dundon's and I really don't understand why he has not already pivoted from the teams' philosophy re: rentals. If Guentzel makes the team potentially a lot better, and most think he does, the team should not risk losing him, particularly to the Rangers. Is there no logic to this strategy?
we have multiple years of history with deadline acquisitions and playoff performance. hard not to see that acquiring talent for scoring and improved depth is the way to go. they have tried with Domi, poolparty, ghost, et al. low-cost rentals yes but not true difference makers. Guentzel is a difference maker. I would also argue Buchnevich as a 2nd option as well.
IMO there is no downside to acquiring Guentzel. Will you honestly not root for this team if for example, Jackson Blake becomes a 30-goal player in the NHL for the Pens and the Canes lose in the first round this year? Not the desired outcome for sure however if you argue this scenario then you should also acknowledge a different outcome, which is the Canes acquire spare parts at the deadline and also lose in the first round. Even if you think the probability of outcomes are very different between these scenarios, neither would be a zero probability outcome.
