I don't think the plan calls for the Rob to get razed. I think they're going to build around it. There will be a transitional year where construction is actually going on around the stadium while we play. http://www.uhcougars.com/sports/m-footbl/spec-rel/061010aaf.html 40K with an option for 50K later.
It would be a bad idea to play at Reliant. I went to UH in the early 90's when they had a good team and were in the SWC. They played at the dome and were only drawing between 5K and 10K fans. It looked empty. Robertson is the way to go.
It was a sell-out. What UH student or alum would go watch a high school game instead of their Cougars? Not happening, cowboy.
