Dallas' Tony Romo complained last Sunday about the noise at AT&T Stadium, which led him to use a silent count against the Houston Texans. It was obvious from Romo's perspective that the crowd was more vocal for the rival Texans than his home team. Since the Cowboys' stadium is more of a tourist attraction than a home field advantage, I wondered if most NFL venues had that same effect on opposing fans. Not if you live in Cleveland and root for the Browns. FirstEnergy Stadium seats 73,200 diehard Cleveland football fans, and they don't appreciate unwelcome guests, especially division rivals. When a Ravens fan decided to act obnoxious and film the crowd's reaction to him after a Baltimore score a few weeks ago, the guy was lucky that he didn't leave FirstEnergy Stadium on a stretcher.
