I do not understand this. I have lived all around the country and I love living in Denver.
Colorado has been a pretty bad team for a pretty long time. Couple that with some contract issues with their star players which, more than likely, gives them a reputation for being difficult to deal with among players and you have a team that struggles to sign UFAs.
A couple of consistent seasons and some time passing between the contract disputes (please god don't let Barrie be another one) and they should be able to attract some players without overpaying them or giving them too much term (basically every UFA contract they've signed the last few years has been).
Fingers crossed, anyways.
