It looks like, at most, there will only be slight variation in the appearance of different first-round sites' floors for the NCAA men's tournament. In my viewing market of Lubbock, Texas, I first got a few minutes of the LSU-Butler contest from Greensboro, North Carolina. Then I was taken to the Texas A&M-BYU game from Philadelphia, which I think will be the primary game for my part of the country in this time slot. I'm also getting some cut-in to the Memphis-Cal State Northridge game in Kansas City.
All the courts have what appears to be an oversized blue circle at center court, with the letters "NCAA," similar to what's shown here.
At Greensboro, the rest of the court did not have any solid, painted-in areas except for the semi-circles above the free-throw lines (in blue). Same for Kansas City.
At Philly, it's pretty much the usual 76ers' floor (which already has a lot of blue), except for the NCAA circle at midcourt.
I have two immediate reactions: (a) for me, with court designs, variety is the spice of life, so I don't like the push for uniformity; and (b) given that there appears to be a single prototype design (as seen in Greensboro and Kansas City), I think it's ugly.
I invite those of you who get games from other tournament sites to describe the court designs you see, in the Comments section of the blog. And, by all means, let me know if you agree or disagree with my opinions.
