Not 100% sure it is right, but just was on CBSSPORTSLINE and making my pool picks and with the proliferation of electronic resale market they show the cost of tickets.
While sure expensive tickets (i.e. good seats) for other teams maybe more, Buffalo tickets start at $229 (closest is Raiders/Cardinals game).
Cheapest is going to Dallas(😝) & Jax (no surprise) $29 & Los Angeles Rams <$40....
My best two stories was always coming to games (1-2/yr) never with tickets and always scalpers.....
1. The 1989(?) Oakland Playoff game. Bought 4 tickets probably $20/ticket and got in went to seats and got comfortable watching one of the great routes of all time until some people showed up to our seats. Before an argument broke out, we looked at our tickets and they were for the divisional game, not the championship..... Oops, but we were in the stadium and a great time.
