I still wouldn't do it. Kessel is the type pf player that you have to give special treatment too, and that doesn't work with the way this team is being built. I want player who want to win, not just players who like to play hockey. Kessel reminds me in a way of Brett Hull, great goal scroer, but didn't like to practice, didn't like the media, almost had issues with staying in shape. Hull did win two Cups, but he wasn't the leader or counted on to be the main offensive weapon on either of those teams. In Dallas you had Modano and Nieuwendyk, Lehetinen and Carbonneau, who were the leaders of the team and Hull was just allowed to do his thing. Same thing in Detroit where they had guys like Shanahan, Fedorov, Lidstrom, Yzerman, Robitaille, Larionov and Chelios. Hull was surrounded by some of the greatest players of all timeso his deficiencies as a player and a leader were masked by great teammates.
Kessel in Calgary would be the best player and looked too, to be the guy. That's not what Kessel is, if you want to have success with Kessel in your lineup he has to be a roe player, not the number one option. IMO bringing Kessel into this team would set the rebuild back, and I am not sure it would get on track while he was on the team.
