The Ravens used their last pick in the third round and the first one in the fourth round on projects.

Oneil Cousins, who was selected 99th overall, is an offensive tackle with an upside but he was a defensive lineman until 2005. There will be a steep learning curve for him in the NFL.

A versatile athlete, Cousins started at left tackle as a junior before moving to the right side last season. But there are questions about how he will hold up against the top defensive ends in the league.

In the fourth round, the Ravens addressed receiver by drafting New Mexico's Marcus Smith with the 106th overall pick.

A former tailback, Smith has limited experience as a receiver. He should contribute right away on special teams but will need time to develop on offense. Smith is not considered a burner but he brings toughness to the position.
