DAVIE — Dolphins cornerback Xavien Howard intercepted Andrew Luck twice last Sunday, then they crossed paths on the field after the game."Man, I didn't even see you," Luck said. "Where did you get your hands from? How did you get the ball?""I just made a play on it," Howard replied, with a smile.The Dolphins have one of the best cornerbacks in the NFL on their roster, and he's 25. This week, coach Adam Gase was asked about Howard, and he brought up Darrelle Revis and Richard Sherman.This
