KANSAS CITY, Mo. (AP) – Romeo Crennel said Wednesday that he shares the frustration of fans in Kansas City over the Chiefs’ 1-4 start while also calling them “some of the best fans in the NFL.” The Chiefs coach served as a spokesman for an organization whose fanbase has been the subject of national scrutiny this week. On Sunday, offensive lineman Eric Winston laid into fans he believes were cheering after quarterback Matt Cassel was injured.  Cassel sustained a concussion in the 9-6 loss to Baltimore. Crennel said he believes most Chiefs fans “felt bad” that Cassel had been hurt. He also said that Brady Quinn is preparing to start Sunday at Tampa Bay.
