‘What’s interesting about the doubleheader is that it bucks convention. The NFL and its broadcast partners typically don’t compete against each other in primetime slots during Monday, Thursday and Sunday night games. Yet, the games in this Week 2 doubleheader will have some overlap, with the Titans-Bills showdown kicking off at 7:15 p.m. ET on ESPN and the Vikings-Eagles billing starting at 8:30 p.m. ET on ABC.’
