Up front, it all begins with Haloti Ngata.
The Ravens' defensive tackle and five-time All-Pro is counted on to generate a push along the interior of the defensive line. If Ngata can win the battle and force teams to worry about him first and foremost, then that frees up opportunities for his teammates to fill gaps to stuff the run or to rush the passer.
Ngata gets his fair share of plays to make in the backfield too though. Over the past four years, Ngata has tallied 17 sacks as a defensive lineman. In 2013, he moved inside to nose tackle and only recorded 1.5 after tallying at least five in each of the previous three seasons.
This part of the offseason is unique in that most players have to stay in shape on their own through their own personal workouts. A lot of them will work out with their own trainers at various locations, all to make sure they're prepared for the grind of OTAs, minicamp and, eventually, training camp.
Ngata is no different. As you can see in the video below, uploaded to trainer Josh Halbert's instagram account:
