What would you like to see? Students closer to court, closed concourse, different video boards, etc.? And more importantly, are renovations possible?
This is a very interesting thread to me. I think the Big Ten schools have done a terrible job of dealing with their basketball arenas, much worse than relative to the football stadiums, and this is coming from a Minnesota fan. (Minn. let their very large and historic brick stadium decay for 30 plus years, spending not a dime on it, then moved to the cheapest, most sterile, stale place ever, the Metrodome, using the "poor' condition of Memorial Stadium as an excuse to do it - PS then managed to negotiate the worst lease known to man) Thankfully those days are long gone.
I am old enough to remember seeing games on TV from the Fieldhouse, and recall the post Lute teams playing a couple of games at the Fieldhouse early in the season (Payne, Stokes team) because CHA was not ready as expected.
I sensed immediately that something important was lost forever for Iowa, as I had heard the Fieldhouse was finished, and was mesmerized to see it in front of me on TV, getting one more night of glory.. Sure enough, later that year when I saw a game on TV from CHA, the atmosphere was lacking. Having said that, when Iowa is good, CHA is pretty good, and way better than at some other places, where they spent a lot of money and ended up with crap. On TV the dead spaces around the court and lack of any student energy is what stands out. It is amazing how a 1970's Arena like Hilton, that as a NBA venue would have been bulldozed 20 years ago, seems so current. Iowa could make things better at CHA, but closing the concourse off is not a great idea, unless it is part of a very big renovation.
Some of the worst Big Ten arenas are the "new" ones like at UW, Ohio State and Penn State, graded on a "curve" of course. They spent a ton of money on these places and they are awful. No energy, seats far from the floor, bad sightlines, and worthless "hockey" seats facing where the goalie would be. The exception to this is the Breslin Arena at MSU, they did this one right.
The Ohio State facility is so vanilla and awful that everyone got excited a couple of years ago when they were forced by a conflict to play a game in the old St. John Arena next door, and there was once again some excitement and atmosphere at OSU. St. John Arena looks like a slightly smaller version of Williams Arena on TV, but in reality it was built in the early 50's and has much better bones.
The other exception is the Maryland Arena, built in the ACC era, and by far the best arena in the Big Ten. Edit, I forgot Nebraska, Maryland and Nebraska are 1A and !B, not sure of order. The old Maryland Cole Fieldhouse would probably be the fourth best arena in the Big Ten if they still used it.
Three arenas from the 60's were not worth spending a dime on and should have been replaced by state of the art arenas with many premium suites, in Mackey, Crisler and the Illinois Assembly Hall. At least the "State Farm Center" at Il. is larger and somewhat more interesting than the other two.
The Indiana Assembly Hall is a abomination and should be torn down for a carbon copy of the Indiana Pacers basketball only facility. IU has the money to do it and that facility has nothing going for it other than its connection to Bobby Knight, and we know how that ended up. I do like Bob Knight, though.
Rutgers is smaller non-descript, but not a bad place, and Welsh Ryan at NW..smaller and... well......
That leaves Williams Arena. I used to think Williams was one of the greatest places ever based upon the impressions created on TV when the team was good and the building was loud, or when I attended in person and sat in the lower level sideline seats during the Clem Haskins era The other side of the coin is being in Williams when the team is bad, when 5000 lethargic fans are watching a Monson or Pitino team lose to South Dakota State. It is extremely uncomfortable to sit in that a which can be overlooked when the team is good. A good number of the seats have terrible sightlines under the overhangs.
I think that my point is that CHA and Williams Arena both have serious issues (very different issues), but I would not trade either one for anything else in the Big Ten other than the top two. (edit three, Nebraska, Maryland, MSU)
Be thankful a huge pile of money was not spend in the last 20 years on a now obsolete facility, or some turd like Crisler or Mackey was polished leasing to a mediocre result.
Missouri, Oregon, Pitt, Nebraska, USC and a few others have done it right recently though.
