Miromanov, Pachel, Kylington and even Hanley are all bigger and far more useful to the Flames than Brannstrom would be. With exception of Kylington each of them costs far less to pay too. Then there are all the NHL ready or near ready prospects Calgary has now who are also bigger, cost less and in most cases will be better than Brannstrom too.
Find another team to take your undersized reject, Calgary has no interest in him at all. Chychrun is who they'd be interested in, he'd be worth much more than just a 2nd if he comes with an extension.
Pachel and Hanley are both waiver pickups from another team, so if anyone is a reject, it's those two.
Kylington is a UFA that just experienced a major crisis with his mental health.
The only one of the 4 you mentioned that might pan out next year is Miromanov, but that's not a guarantee.
And just because a prospect is big doesn't mean he can do anything else at the NHL level.
Interestingly, you say Calgary has all these NHL ready or near ready prospects on defence that will all be better than Brannstrom, but you didn't name a single one.
I thought Brannstrom would be more affordable for Calgary because he would be less expensive than Chychrun.
But if you prefer to keep scraping the bottom of the barrel with waiver pickups, then knock yourself out.
To each his own.
