Doubt they would shell out a 1st a 2nd and olofsson.

the team needs to continue to build and shelling out a young player and 2 high draft picks isn't really in the cards.

If they keep Eichel they more than likely would get a stop gap 2c and wait for Mitts or Cozens to permanently take that role.

I get what you're saying regarding the picks being given, but BUF needs to do something on the ice now, and waiting another 2-5 years for whoever they use those picks on isn't the answer.
Whoever they draft with that 2022 1st will most likely be some 18yr old kid who will take maybe 2+ years to be an effective NHL'er, so that's already a min 3 year wait whereas Mony gives them a proven center right now.
Monahan gives them a perfect 2C behind Eichel and a guy who has a proven track record of 30+ goal seasons.

I've seen worst trades but the way the Sabres look that 2022 pick is likely a top 3 pick, my counter would be Reinhart, Olofsson, Miller, 2021 2nd 2022 1st for Monahan and Tkachuk

No thx

Oh no no no, Tkachuk is not part of the discussion in any way.
Everyone tries, but it's an absolute no from the Flames perspective
