It could go either way from here.
We have a number of high potential prospects (Pettersson, Dahlen, Lind, Gadjovich, Juolevi, Demko, Guadette, etc.), some more guys who trying to establish themselves at the NHL level (Virtanen, Goldobin) and a few more seem to be well on their way (Horvat, Boeser, Stecher, Pouliot). We also have decent goal tending and sufficient utility / support players.
But look at Calgary for comparison. In the summer, people were saying they had a top 3 defense with Giordano, Hamilton, Brodie and Hamonic. They have star forwards in Monahan, Gaudreau, Backlund, some emerging players in Tkachuk and Bennett and some good prospects in Foo, Klimchuck, Valimaki. Mike Smith has stabilized their goalie situtation, so they were expected to be a playoff contender this year, but currently, they are sitting 1 point ahead of the Canucks and 2 pts back of a Wild Card spot.
That said, it's hard not to be excited about the future when you see Boeser on a PPG pace with 17 goals in 30 games, and Pettersson setting the SHL on fire. Juolevi is having a really solid year in Finland and Lind is tearing up the WHL. It's not hard to imagine a very good team with these as the future core.
The biggest threat to the future would be if Benning panicked and signed another aging veteran to a multi-year deal.
