Look on Google Maps. The opening is smaller than one might think from afar. But you are right the real Rent has 3 blue sections on both side with the middle one on the 50. UConn related - the big lights in the 4 corners represented, the smaller lights on top of the stadium, and the mini press box (aka known as "Brutal DJ Booth"). Not UConn related - the 4 rows of blue and is that an "H" on the 50?
I also looked up the builder, Ellerbe Becket, and all their stadiums. Nothing matches the Rent. Has to be the Rent doctored somehow or its just the Bizzaro version of Rentschler Field.
