I might have to shower after I post this BUT...from my knowledge of the MSG capacity- 20,789 and fact the Liberty drew 9,879 in their last year there. The team must host 17 home games in from mid-May to mid-August and their is a cost to open and operate the facility-margins were probably too thin.
As the "World's most famous arena", it hosts concerts for "A" listers and occasional other events that conflict with the WNBA. These events Sell out to the maximum capacity at a premium ticket price vs. the WNBA.
Dolan has been more than fair with the Liberty, especially considering how many other NBA owners dumped or simply just left their teams. To open an venue for less than 50% capacity, not exacting premium pricing and limited concessions, not to mention the sky box issues, I do understand their move. Now, I just wish it could have been to a higher seating capacity like many college venues have of 8,000-10,000 but I don't know if any exist within the footprint of NYC. Harbor Yard might be the closest and that's bit too far.
I wish the new owners well but they too may find that the cost to open and operate will be prohibitive unless they don't worry about their margins and just want the Barclay Center open.
This simple fact is the WNBA has an image issue that prevents it from being a true stand-alone professional sports league with healthy revenue. The positive is it happens to be the best women's league in the world that is trying hard to grow it's appeal in year 23...
Now I must go and cleanse myself from the stink of defending James Dolan...yuk...
