MIAMI GARDENS — After the edge defender Thursday came the offensive tackle Friday for the Miami Dolphins. The Dolphins selected Houston’s Patrick Paul in the second round of the NFL draft, pick No. 55. At 6 foot 7 and 331 pounds, Paul is an experienced left tackle with 44 college starts who was a first-team All-American Athletic Conference selection three years running. Paul tested well at the NFL scouting combine, running a 5.13-second 40-yard dash and bench pressing 30 reps.
