Frustrated with early playoff exits, the Kansas City Chiefs made significant changes this offseason. It is not often that you see an NFL team voluntarily trade a more-than-capable starting quarterback, but that is exactly what happened when the Chiefs dealt Alex Smith after arguably his best NFL season (87.1 overall PFF grade, T-sixth among quarterbacks). The Chiefs also shipped off their biggest playmaker on defense by trading away disgruntled All-Pro cornerback Marcus Peters. Despite the roster shakeup, the Chiefs remain legitimate playoff contenders as they vie to defend their AFC West crown.
