We examined the latest NFL news and notes and your Bills/NFL questions in the OBL Friday Fan Mailbag before Bills-Chiefs. We heard from WR Emmanuel Sanders, OL Spencer Brown and S Jordan Poyer. NFL Films senior producer Greg Cosell shared his preview of Sunday's Bills matchup in Kansas City. He shared his thoughts on how the the team can defend the Chiefs offense, including ways to limit QB Patrick Mahomes and the run game with a new-look offensive line paving the way. He went on to discuss the Bills offense, the difference between last year and this year, the effectiveness of the run game, the diversity in the pass game and Dawson Knox's emergence (51:30). We found out what Bills Mafia is up to this weekend in this week’s Tailgate Friday.
