KANSAS CITY, Mo. — Chiefs coach Andy Reid could have quite the pleasant problem come Monday night.Pro Bowl running back Jamaal Charles is expected to return to the field after missing last week’s win in Miami with a high ankle sprain. And that means Reid will have to figure out how to distribute touches against New England around a very crowded offensive backfield.Knile Davis ran for 132 yards and a touchdown against the Dolphins. Throw in Joe McKnight’s play, which included six catches for 64 yards and two scores, and a few touches for Cyrus Gray and suddenly the Chiefs have an abundance of talented runners just waiting to tote the ball.Even running back-turned-wide receiver De’Anthony Thomas finally could be available against the Patriots.
