The biggest sweat for bookmakers at Seneca Creek Casino in downtown Buffalo often begins before the Bills game even kicks off, and it's not the heavy betting action on the red-hot hometown team that concerns them most. Instead, as Bills fans arrive at the sportsbook each Sunday, the staff's focus is on the furniture.

'You see the blue start coming in, the Bills logos, and we've got to calm them down a little bit. These guys get super excited about their team,' Gavin Mercado, who oversees the sportsbook operations at Seneca's three Buffalo-area casinos, told ESPN with a chuckle. 'We have to kid around and tell them, 'Listen, we have some tables around here, we can't have you guys jumping through them.'

The tables in the sportsbook have survived the regular season, 'thankfully,' Mercado said, but it's playoff time now, and betting on the Bills is all the rage in Buffalo.

'The energy keeps growing week to week,' Mercado said.

The Bills are 6.5-point favorites over the visiting Indianapolis Colts in Saturday's first playoff game of the weekend. As of Thursday evening, about 80% of the bets on the game were on the Bills at Seneca sportsbooks.

Nearly half of all bets -- 47% -- on the odds to win the Super Bowl have been on the Bills at Seneca's books. There are nearly five times more bets on the Bills than on the Kansas City Chiefs, the Super Bowl favorites and the second-most heavily bet. In comparison, at William Hill U.S. sportsbooks around the nation, five teams have attracted more Super Bowl bets than the Bills: the Chiefs, Green Bay Packers, Tampa Bay Buccaneers, Seattle Seahawks and Pittsburgh Steelers. At Seneca, there are more Bills bets than those five teams combined.

The betting interest on the Bills has expanded outside of Buffalo, including some large wagers. DraftKings reported taking a $9,900 Super Bowl bet on the Bills at 12-1 that would win a net $118,800, and William Hill U.S. said it took at $6,000 bet on the Bills at 35-1 earlier in the season that would pay a net $210,000.

'We don't do very well with the Bills,' Nick Bogdanovich, director of trading for William Hill U.S., noted in a company release. 'We have a lot of money on Buffalo.'
