The Baltimore Ravens are signing free agent running back Danny Woodhead in a surprising move. But the biggest questions are how he fits into an already deep running back corps and how he fits into the Ravens’ scheme at all.

The attributes Woodhead is known for are his speed and agility. Not the biggest back by a wide margin at 5-foot-8, Woodhead has made his money in the NFL by being small and quick enough to gash defenses occasionally.

However, at 32 years old and coming off an ACL tear, does Woodhead have that same ability? Without seeing him on the field personally, we just won’t be able to say for certain until training camp. Then again, it might not be his quickness and explosiveness Baltimore is solely looking for.

One thing quarterback Joe Flacco has missed more than anything was a pressure-relief valve. When at his best, Flacco had running back Ray Rice out in the flat as an easy completion and chance to move the chains. If his first reads weren’t there, Rice got the ball and a chance to make something happen with it, which he often did. With speedster wide receivers, having a running back in the flat makes complete sense, since you see far less competition for easy yards. That’s why you often saw fullback Kyle Jusczcyk take on that role in 2016.

When you look at the roster as it stands right now, that’s exactly what the Ravens are missing. With the departure of Juszczyk to the San Francisco 49ers on a massive deal, the Ravens are missing their outlet valve in a big way. They have bigger backs capable of pounding it inside, but no one with the agility to bounce to the outside and make a play there. That is how Woodhead has made his career in the NFL and is by far his biggest strength.

For Woodhead’s career, he has 267 receptions for 2,498 yards and 17 touchdowns.

Looking at the depth chart from a typical point of view likely won’t work for Ravens running backs any longer. Expect a triple-headed beast this season as Baltimore tries to take charge on offense in all directions.
