KANSAS CITY, Mo. (AP) — Casual football fans might describe the Chiefs offense as a go-for-broke, throw-it-deep bunch built around flat-out speed. Those that have watched Kansas City this season see something entirely different: a group just as willing to take dink-and-dunk throws all the way down the field. Most of that is due to the maturity of Patrick Mahomes, who has found ways to reconcile his desire to hit the big play with the reality that it’s not always open. The result is a Chiefs offense that heads into the Super Bowl against Tampa Bay that may be more dynamic than ever before.
