I don't think it is being sick of waiting. The lease is up in 4 years. Projects such as this don't go up overnight. Four years out is the time some plans need to be set and things need to start moving. If the Browns are going to continue to play in the stadium through any construction, that means you can't work on things year round, which will add to the timeline. Haslam and the NFL also have some history on the last time the city and team were discussing a new stadium project. Regardless of who you want to blame, things were fumbled away.
The NFL want domes, that is pretty clear. The city needs to build a dome for year round use. The ROI will be seen much sooner. Those acres in Brook Park are a good buy for the Haslams no matter if it is used for a stadium or something else. My thought on something else would be to move the Casino out of downtown and stick it out in Brookpark on the Haslam property. A connector to the airport via underground tram would be easy enough. Make Cleveland a weekend gambling destination. Walk to the terminal from you airplane, get on the tram and you 're in the casino/hotel area. Have a theater where you could book name act entertainers. The possibilities are numerous. Including a stadium if the city keeps dorking around. Unlike Model, Haslam has the money to do anything he wants. He is a man of action. He isn't going to sit there doing nothing while others hem and haw over things.
