The problem with Coleman is actually a combination of three inter-related things.
First, it was built during a time when multi-use facilities were in vogue. Think the really old round stadiums in Atlanta, Pittsburgh and Cincinnati. Not that Coleman looks like any of those -- it doesn't. The point is that it's kinda sorta passable for a lot of things, but not really good at any of them.
Second, and a function of #1, is that the first rows of permanent seating (as opposed to super-premium courtside folding chairs) are too far away from the court. Creates a lot of distance between the crowd and the action and significantly diminishes the home court advantage.
Finally, it's just too big. In combination with the distance created by #2 (which is itself an outgrowth of #1), the cavernous size means the seats above about row 25 or so are really high.
Bama Moon's suggestions about seat location are good.
If you can score a parking pass, that would be ideal. About half the old parking lot has been commandeered for expanded basketball facilities (not a new arena -- coaching, training and meeting facilities), which are currently under construction. Parking now often involves the softball lots and a bus ride.
