Mailbag: Which undrafted rookies have best chance at making the Ravens?

It's time to click open the second part of our weekend Baltimore Ravens mailbag ...

@jamisonhensley: Receiver-returner DeAndre Carter of Cal State-Sacramento and safety Nick Perry from Alabama. This is speculation at this point because this comes after watching one two-hour rookie practice. Carter has great quickness and has experience returning the ball. Ravens coach John Harbaugh said the team's returner could come from this undrafted rookie group, which bodes well for Carter. Perry started on a pro-style defense at Alabama, and the Ravens need to add young, quality depth at that position. As we all know, general manager Ozzie Newsome loves players from his alma mater.

@jamisonhensley: Ravens coach John Harbaugh recently said he expects a big year out of Marlon Brown. He would've had a bigger opportunity to contribute if the Ravens hadn't drafted Breshad Perriman in the first round. Brown's best shot at getting on the field is in the red zone. He caught seven touchdowns inside the 20-yard line as a rookie in 2013, and it's bizarre that the Ravens never targeted him there last season. The Ravens need to get Brown more involved closer to the goal line because of his size.

@jamisonhensley: On paper, I believe this Ravens team is better than last year's. It's better primarily because the Ravens solidified the weakest part of the team when they signed safety Kendrick Lewis and nickelback Kyle Arrington in free agency. The Ravens also filled their needs early and often in the draft. There are certainly questions that the Ravens need to answer. Will the Ravens be able to stop the run without Haloti Ngata? Can Perriman replace Torrey Smith as the team's deep threat? How much will the Ravens' pass rush suffer without Pernell McPhee? The Ravens have the pieces in place to be a legitimate Super Bowl contender. But that's contingent on the new additions stepping up.
