Andy Reid is willing to adjustYou may have heard local media and certain bloggers talk about the Chiefs’ offensive identity shift to an under-center, run-centric approach this offseason.I can’t speak for everybody, but even the most optimistic version of myself didn’t see this coming.Walker gained 148 of his 173 rushing yards on under center runs against the Broncos.

On the opening drive, Delane manned up wide receiver Courtland Sutton, sticking to his hip pocket and covering up the route so well that when he turned to defend the pass, he barely needed to react, and he had an interception.Shortly after, Delane left the game with a shoulder injury, but one play is all it took for Delane to show why he could be one of the next elite cornerbacks in the NFL.Up front, defensive end R Mason Thomas ignited a pass rush that tormented a Broncos offense that surrendered the fewest sa
