I can understand being worried about missing out on Demidov, but there's ample reason for Chicago to jump in on this.

The Blackhawks are virtually bringing in 4 1st round picks in this deal, with 26th oa Mesar, 31st oa (would've went earlier if not for 'the incident') Mailloux, Winnipeg's 27th oa pick, and 5th oa this year, which moves Chicago down only 3 spots. Chicago's prospect pool is underratedly empty, with almost no right shot prospects in general, which is a sneaky important reason for the Hawks to like this deal as well.

The big question though is whether the guy 3 spots after Demidov is worth these prospects, and for Chicago, the answer is definitely yes considering it's likely they'll end up with one of Eiserman or Lindstrom, the former having a higher ceiling as a prospect and the latter having a better fit along side Bedsy.

Montreal fans would be ecstatic to hear they moved up. Though all of the picks and prospects they moved for this are great young players that'd be hard to move off of, Habs fans to this day are salty about selecting Reinbacher over Michkov, so for the team to make up for that by adding Michkov 2.0 would turn Kent Hughes into a saint in the city.

Montreal has a ton of prospects at every position without the roster spots to go around, with top 6 roster spots constantly up for grabs, and a virtually solved D core, the Habs have no space for another 4 prospects that they can't give minutes to.

As mentioned earlier, the team skipped on Michkov, and though I agree with the Reinbacher pick, I also agree that Montreal still has not solved the problem that is their barebones top 6, and if sacrificing a ton of prospects you don't need is the solution, make that call to Chicago on draft night.
