Not much they could've done. They were just a few years out of being all in on a Memorial Cup run.
Edit: Worth mentioning too. It's looking like they'll play Saskatoon in the first round of the playoffs. Regina isn't one or two good players away from competing with Saskatoon, they'd need quite a bit to stand a chance. And after that stands the Winnipeg Ice, Regina couldn't have built a team to be competitive with them. Having the Blades and Ice in their division was just a deathblow to their chances anyways, it was a bad year for them to be competitive.
