Dont think its ego as much as how comically lopsided that team would be with two 25 minute a night generational centres.
As it was Ive always suspected the gretzky era kings struggled to make do with ahl-level depth players to compensate for the salary & usage needs of having the team built around Gretzky.
Said it before, and Ill say it again, its obviously montreal if the silly cant-let-our-rival-win-the-cup logic gets thrown out the window.
Montreal gets a generational player to build a genuine new dynasty around. Lindros' presence pretty much instantly secures the capital needed to build the bell centre. The gnawing organizational issues with Roy being bigger than the team because he basically was the team go away. Other pieces like keane/carbo also have their own reasons for wanting to move on
On the flip side, anyone that knows Roys personality knows a nordiques cup is basically a lock once hes moved. Even without including Roy in the deal, a package of say any 4 or 5 of muller, corson, keane, carbonneau, desjardins, schneider, Lefebvre, or Leclair would make the nordiques a staggeringly dangerous team with excess experience, defence, checking, secondary scoring...
I think the real question is whether montreal could have ponied up the cash, and how aware the canadian teams were of the coming crunch that the 70c canadian dollar would put on their budgets. Did NHL teams at the time have financial forecasts available showing how far behind the US teams they would be by 2000? (And inferring from that, Lindros to Montreal would make a lot less sense)
