Monahan without Gaudreau is just another 45-50 points C. That doesn’t get you a top D prospect and a top 10 pick.
Avs offered a 20 years old former 10th overall, a top 50 D prospects, a 1st, 2nd and 3rd and it’s still not enough for you? These two would be top 3 in your system so I’m not sure what’s your point here
*facepalm*
First, Timmins is not surely better than Kylington, Andersson, Hanifin, or Valimaki, all U23 players in the Flames system. Being a top 50 D prospect means very little. The D prospect the Flames would want back is the one who can be an impact player, and that is Cale Makar.
Second, Jost's draft position doesn't define his value. If he turns out as a decent middle six forward along the lines of Michael Frolik, that does not satisfy a need for the Calgary Flames, even if that's solid value at 10th overall. I like the player. But he's a spare part. The forward the Flames would want back is one with a higher ceiling, someone who can fill the void lost by trading an annual 60+ scorer, and for that we would require the highest possible first round pick and let our own scouting team find that player, ideally but not likely Jack Hughes.
Third, you don't average 30 goals and 34 assists per 82 games for the last four seasons (while being U25) just because you play with a good player. Every good player in the NHL has always had a good linemate. There is no way Monahan isn't a top six forward for the Avalanche, even if he's not as good as Nathan MacKinnon.
Fourth, that first is likely to be a 16th to 27th overall pick. While picks in this range can turn out well, they are usually not that great, - typically ending up as middle six players when they don't altogether bust.
Fifth, when a team is trading away their so-called number one center, the second and third round picks mean zilch. You could throw a dozen second and thirds into the pot and they're still second and thirds.
Finally, just to recap, you are offering middle six forward talent and shot-in-the-dark defense talent for a young perennial 30 goal scorer with term. Yeah, that's not a fair trade and if you don't want to make a fair trade, we don't want to make any trade.
At this point Makar and even your first are magic beans, and while the Flames would make that trade due to the fact that they need those magic beans to work out to step up to the next level while the Avs could use something more proven to round out their roster. Offering spare pieces for a 30/30 player is a sure way to get laughed off the phone.
