It may seem like a cakewalk for Patrick Mahomes and the Kansas City Chiefs in Week 14, but the Miami Dolphins are no longer a team to consider a joke.The Dolphins are currently 8-4 and stand in second place in the AFC East. In first place is the Buffalo Bills, and the Dolphins have a chance to take over first place in the next few games.After the Pittsburgh Steelers were knocked out of their perfect season by the Washington Football Team, the true AFC contender is now the Chiefs. The defending Super Bowl champions are 11-1, and they avenged their only loss when they beat their AFC West rival Las Vegas Raiders a couple of weeks ago.It will certainly be a good test for Miami's rookie quarterback Tua Tagovailoa, who has only played against one really good defense, being the Los Angeles Rams, and struggled against a depleted Denver Broncos' defense.Kansas City Chiefs at Miami Dolphins Betting OddsKansas City's odds: -7.0 (-110)Miami's odds: +7.0 (-110)Spread: The Chiefs are -7.0 favoritesKansas City Chiefs at Miami Dolphins Picks1.
