I would have absolutely zero issue adding to Kylington to rent Bert.

Vrana doesn't start the conversation for Rasmus Andersson.

With the acquisition of Weegar, Kylington is the odd man out and is the Trade Bait we have to offer for a Forward

We’d need retention on Bertuzzi at an additional cost, sure a 2nd or I’d gamble with Kubalik but he’s not enough and we don’t want picks, we want guys that can contribute now or the next season or two, since you are correct we’re making a run for the cup

Fabbro & Vrana are of little interest to us since we can’t bank on them being healthy and available, leaving us short handed or scrambling to create new line chemistry come playoff time

Kylington makes sense for DET AFAIC. He’s young and has room to improve as a puck moving & mobile d-man who can play both sides. He’s just not needed in CGY as much as another forward

I could see a Kylington + 1rd Round pick -23, for Bertuzzi with 1m+ retained.
2 caveats - Bert is coming up on UFA 23 and is likely looking at at pay rise looking at how he's performed. Also, how will Kylington's injury affect him? How long is he out and how good will he be once he returns?

All this said, there are other options for the D-line available all things considered. Edvinsson is going to be joining soon enough along with Albert Johansson and Lindstrom is already playing a pretty solid RD. This trade was originally to look at what the reaction would be to get Andersson for Vrana. Although plenty of Detroit fans borderline would die for Vrana, I am not so convinced myself (but would love to be proven wrong). I wouldn't fall off my chair in chock if I saw that trade happen considering the needs of either teams.

I like Andy... But no chance.. Vrana is 3rd in NHL in pts per 60 ....just needs to stay healthy & he's a 40 snipe goal guy..until we have more young scoring fwd depth we'll keep our rare snipers.. UNLESS it gets a FRANCHISE CENTRE OR GENERATIONAL #1 D .. But thanks 👍
