I can see that. More so because of negotiations skills. I also was not a fan of an accelerated rebuild with a heavy focus on skilled forwards who play "small'.
By the time Dubas got there the club was already "built" with a 100pt season behind them and a bunch of young fire power. His directional choices were not really part of a rebuild any more so that's maybe a different area of discussion.
Hindsight is 20-20 but building from the net out could still still have happened with AM, Willie and Mitch. Its like Lou forgot he had Stevens, Niedermayer and Rafalski in Jersey. He could have thought the old Devils teams were just too different to emulate and maybe focused on the more Leaf-like Hawks teams but the Leafs didn't have close to a Keith, - Seabrooke - Hjalmarsson trio either
If the club had made an effort in the post thug years to add some more defensively aware quality D that would have carried into the rebuild. Guys like Franson, injured Gunnarsson, Roman Polak came and went and that was the level of guys they used, and when they left, no real effort was done to upgrade. They did add Gardiner who looked like he could be something but really he just fell into their lap
It starts with Burke and the Kessel trade where the club was under the false illusion they were close to competing but in 2014 they passed over Niskanen, Stralman, Ehrhioff, and Oduya in 2015. Not superstars but UFA players that would have been there to anchor the big 3 when they arrived. Now long term they weren't really locked into defensiive mediocrity by the cap until the Tavares signing which took them out of Hamilton and Pietro, and maybe Larsson and Oleksiak,
Right after the Shanny hire they should have started building the D right but so far three GMs have not figured that out..
