Training camps are still in the distance, but USA TODAY Sports is providing five things you need to know about every team in the NFL to catch you up on the offseason. Today, the Miami Dolphins …

1. The defense is banking on young talent to step up

The Dolphins won 10 games and made the playoffs for the first time since 2008 despite a defense that was the fourth worst in yards allowed (382.6 per game) and tied for worst in average yards per carry allowed (4.8). That explains why they used five of their seven 2017 draft picks, including the first three, on defensive players. They are hopeful their first-round pick, defensive end Charles Harris from Missouri, will make an immediate impact as a pass rusher, eventually taking over for veteran sack-master Cameron Wake, 35. The Dolphins also are counting on linebacker Raekwon McMillan, their second-round selection from Ohio State.

2. Tannehill is healthy — and ticked off

Quarterback Ryan Tannehill has recovered from the left knee injury that sidelined him for the final three games last season and is participating in team workouts. “He looks normal to me,” coach Adam Gase said. “He looks like he did last year. He moved around fine. He’s got a good edge to him that I like right now. You can tell that he wasn’t real happy about getting hurt. I know he’s really trying to make sure he’s one of the reasons we’re taking the next step.” Tannehill, who turns 29 in July, had a career-best 93.5 passer rating before the injury.
