You say that, yet both teams did just as poorly as Chicago did this season. Wouldn't it, then, be logical to assume that when Chicago does get some decent top level talent, they'll be able to get significantly more out of them than Anaheim or Columbus can? Hence, the prospects for future might be better, especially considering that Chicago metropolitan area is a ~10mil population market and the ownership will have all the incentive to build a strong contender around Bedard.
Sure, they have one of two contracts they might rather not have, such as Seth Jones, but overall Blackhawks have over 40 million of cap space and can do quite a bit to improve their team over the next few years. It's a much better position to be in than if they had been terrible while having next to no cap space and tons of players locked up long term.
Take Montreal Canadiens. They only have some 10mil of cap space next year, and several players locked up for an eternity. It's much more difficult to imagine how that team would improve than it is to imagine Chicago Blackhawks doing so.
