289 goals allowed was 2nd worst in the East, and 4th worst in the league. One playoff team allowed more than 250 goals - and that was Montreal who also had a -20 goal differential and most seasons doesn't make it. The top 7 teams in fewest goals allowed in each conference made the playoffs.
If you can't get a new goalie (not sure who was wanted but demko/allen re-upped, and gibson had a M-NTC), then you have to improve the players up front. Most of the players they moved on from - Clifton, Cozens, Jokiharju, peterka, lafferty - were not putting in the level of effort needed in my opinion.
