Sure, the tear-down is done. But then comes a year (or two) of bottoming out. That's important to remember. The Rangers need to draft higher than 7th and 9th and hopefully they will in 2019 and 2020.
But no UFA's will be kept past the deadline unless the Rangers are confident that they will re-sign. So if Kreider hasn't signed an extension by february next year, he will surely be on the market. The same goes for Namestnikov, Fast and Vesey.
