It doesn't make them king of shit mountain, it probably increases their odds of being one of the two teams besides Carolina that makes it.
Maybe Philadelphia and Pittsburgh aren't better than Columbus. Maybe they are. Maybe New Jersey takes a playoff spot back next year. Maybe the Islanders and Flyers keep improving with their relatively young cores. Actually, both of the teams behind Columbus had more wins, and regulation wins, than Columbus did this year.
But Columbus isn't the place you go if your goal is playoffs. Again, the delta in the differences between Detroit and playoffs, and Columbus and playoffs this season was negligible, virtually zero. Columbus doesn't represent a better chance to make it than Detroit.
But he will have the option to go to teams that not only have much better chances to make it, but have actually done so in the last 5 years, and have won a playoff series. So why would Columbus be in his top few choices?
