Quoting: OldNYIfan
Backlund is a center, so the attempted comparison there fails. As to Coleman, Iafallo had more points in fewer games in a down year (for him) and is twice the defender Coleman will ever be, and is almost 20% cheaper, so the idea that Iafallo isn't an improvement is kinda puzzling. (Iafallo also had more points than Dube, who would be the other, true comparison.)
As I said, it's perfectly reasonable to decline the offer, but to characterize it as "pretty bad" is an error in evaluation, especially if the main issue is Iafallo vs. Coleman (who is three years older and signed for two seasons more, until he is 35).
Backlund, Coleman and Dube > Iafallo, especially when you compare their ATOI:
Backlund 12G+27A=39PTS/82GP = 0.48PPG with 17:07ATOI of which 2:01 was on the PK (his GA/60 was 7.6) and 1:26 on the PP
Coleman 16G+17A=33PTS/81GP = 0.41PPG with 14:49ATOI of which 1:29 was on the PK (his GA/60 was 4.0) and 0:18 on the PP
Dube 18G+14A=32PTS/80GP = 0.41PPG with just 12:50ATOI of which 0:48 was on the PK (his GA/60 was 5.5) and 0:50 on the PP
Iafallo 17G+20A=37PTS/80GP = 0.47PPG with 18:30ATOI of which 1:38 was on the PK (his GA/60 was 9.3) and 2:45 on the PP
With 25% more Ice Time than Coleman (most of which was PP time) and playing in their Top-6, I'd expect Iafallo to have way more points than Coleman. Iafallo had 45% more ice time and 3 times the PP time Dube had too. Another way these 2 Flames players have more impact than Iafallo is Dube's twice as Physical, but Coleman is substantially = 3x more Physical with his Forechecking.
I expect Dube to have a Breakout Season if given 14:00-16:00ATOI. I also expect Coleman to be much better in his 2nd Season with the Flames, as he traditionally takes a while to get comfortable and familiar with his new team and had a slow start this season. If we needed or wanted another Left Shot Forward, I think we'd just bring up Jakob Pelletier or simply sign either Victor Rask for < 1/4 or Sonny Milano for less than 1/2 of Iafallo's Cap Hit.
So long story short, Iafallo wouldn't be an upgrade or help us at all, neither would a 3rd Round Pick and I doubt Sean Walker is any better than Michael Stone or Nicolas Meloche, so there's nothing there to help or convince the Flames to give up their 1LD and Former 5th Overall Pick in Noah Hanifin when they need a 0.80-1.00PPG+ Top-6 C or RW, ideally with a Right Shot, which we may already have in Toffoli, but a 2nd Right Shot Sniper (like William Nylander or much cheaper Victor Arvidsson) would be nice OR a Centre (like Nick Schmaltz), so we can move Lindholm back to RW again
The reason Nylander might work is because TOR needs Cap Space, so this Trade would improve their Defense and solve that problem, but like the LAK, who also need Cap Space, they could & should simply move Kerfoot out to sign Sandin and be Cap Compliant and LAK should simply move Walker out to sign Durzi.
