If you're a linebacker, and you're picked by the Ravens, consider yourself lucky. It seems they hit on every linebacker in the draft, so I'll defer to GM Ozzie Newsome, one of the best GMs in the business.
SB Nation's Baltimore Beatdown explains the pick:
The knock on Utah State's Bobby Wagner is is smallish height (6'0, 241 pounds), but his body of work on the field speaks for itself. He is a four-year starter, two-year captain and three-time All-WAC Conference selection. A 40-yard dash in the 4.4-4.5 range with a 39.5" vertical leap proves this guy plays bigger than he actually measures. Any doubt whether he could play with the boys in the bigger conferences was dispelled when he was named the defensive Most Outstanding Player of the North team in the 2012 Senior Bowl with seven tackles, one for loss and an interception. Other than a bout with pneumonia, which caused him to miss the Combine, Wagner has been injury-free in his collegiate career. The Ravens have been watching him closely, going to his pro day as well as bringing him to Baltimore for further review. With the loss of OLB Jarret Johnson to free agency and ILB Ray Lewis not getting any younger, this guy looks to be a fixture on the Ravens great defense for years to come.
