Colorado Avalanche have won a Stanley Cup and Arsenal was runner up in 2015-16...Denver Nuggets have not won a title, but have had some stellar seasons...Is it Robert Kraft?, No, however, there have been some great owners without winning championships. William Clay Ford of the Lions & Jeffrey Lurie of the Eagles for example and Lamar Hunt of the Chiefs only won one. There are so many across sports that have done so much for their team and their city, but have not hosted a trophy.
Spanos for example has never won anything either, so that is a bit unfair, although ESK needs to get his football team into the playoffs because until he starts doing that, he always be looked upon as a loser. Even Madame Georgia had a run from 83-89 and then from 99-2002.
