Back in 1994 I spent a weekend in Indianapolis watching sports at the Hoosier (later known as RCA) Dome. On Saturday I went to see Indiana vs Kansas in college hoops - nearly 47,000 on hand in what was just an amazing atmosphere. Roy Williams and Danny Manning vs the General Robert Montgomery Knight and Damon Bailey. Probably a top 5 all-time sporting event I've attended...and I've been to a whole lot.
Next day watched the Colts and Dolphins in the Dome. Probably one of the worst 5 events I've attended. Football in the dome was awful. It did not feel right at all. Place was packed but it was just lacking in every area. First, and what will be the last indoor football game I will attend. Just no.
I get what Bubbler is saying regarding injuries, definitely respect that thought. I still believe that football (and baseball) should be played in natural elements at all levels.
