MIAMI GARDENS — The Miami Dolphins have a chance to stretch their successful late-season run with a victory Sunday at Houston. But it won’t be easy. In fact, trends say the Dolphins (6-7) are unlikely to defeat the Texans (8-5), who are coming off a bye, because the Dolphins are on the road in December. However, quarterback Tua Tagovailoa has been playing the best of his career, wide receivers Tyreek Hill and Jaylen Waddle sprung to life in last Sunday’s 32-26 overtime victory over the New York Jets, kicker Jason Sanders hit a 52-yard game-tying field goal with seven seconds left in regulation and the defense clamped down on the Jets late in the game. So the Dolphins go to Houston with some momentum. We’ll see if they can maintain it. In that spirit, here are five things to watch for in Sunday’s game: Dolphins’ ineffective run game Yes, we’re talking about the lackluster run game once again because they’re only averaging 59.4 yards per game rushing.
