First, we are talking some years in the future.
I was there when Carmichael was built. I was there when the first game was played there. Compared to what was being used - Woollen Gym - it was an enormous upgrade. Of course, at that time men's basketball was the only sport played there. Wrestling and fencing, iirc, were still in Woollen. There were no women's sports, unless you counted cheerleading.
Money was a huge issue then. Carolina desperately needed dorm spaces, and the money went to Ehringhaus, Craige and Morrison. To build Carmichael, the University had to "game" the system by telling the state that Carmichael was just an extension of Woollen, and would be used as a multi-purpose venue housing concerts, guest speakers and the like. Unfortunately the sound was awful since the area just behind the hydraulically-activated stage was the outside wall of Woollen.
In time, it became obvious that Carmichael would never be adequate for the great UNC men's program under Dean Smith, so the "Dean Dome" was born. Carmichael became the home of WBB, and so it has been for the past 52 years. It seats 6,000+ but very few games actually sell out. There are two concession stands, and for most games only one of them is open. In 2009 there were extensive modifications that made it more compatible with the needs of TV; seating was upgraded, scoreboard upgraded, and still it is rarely sold out - the recent SMU game was 2500, less that 50% capacity.
No doubt that some things needed upgrading, like the WBB offices which, if you try to enter them now you will politely asked to get lost. The former WBB museum is now a gathering place for Ram's Club donors. The re are no spaces suitable for pregame activities. Parking is terrible. A new facility may, if designed properly and if men's basketball doesn't totally dominate the layout, could be an improvement.
Still, you have to wonder if we will create a Syracuse-type situation where a few thousand fans are in a building designed for 20,000. See what that does to our recruiting potential.
To me, Carmichael for all its limitations, is "home". I don't think I want to lose that.
