LONDON -- A look at Kansas City Chiefs players who were “up” and those who were “down” in Sunday’s 45-10 win over the Detroit Lions:

UP

CB Sean Smith: He battled with Calvin Johnson for much of the game and while Megatron made his share of plays, Smith did too. He had an interception and broke up three passes.

QB Alex Smith: He rushed for a career-high 78 yards and a touchdown, but his most impressive play came in the fourth quarter, when he drilled a throw to Jeremy Maclin in the end zone for a 17-yard touchdown.

S Ron Parker: He had two of the Chiefs’ six sacks and broke up a pair of passes.

DOWN

TE Demetrius Harris: He dropped a pass, which was about the only thing the Chiefs did wrong.
