It's crazy to think its going to be a 5 year rebuild. Especially when you started out with literally nothing. There were no prospects in the pipeline when they tore it down, there was no good to elite NHLers on the team when they drafted Bedard. 7-9 years is a much more realistic time frame for your prospects to develop to be great to elite players. After 7 years, you hope to be contending for the playoffs, 9 years you hope you are winning your division/championships.
Point me to a team who started out with nothing and became a contender in less than 7 years. You can't find a team that did that. Most teams who had a 1st overall pick had players around those picks to help them. Chicago had nothing.
