Round 6, 203rd overall: C Ryan Jensen

Round 7, 238th overall: WR Aaron Mellette

Round 7, 247th overall: CB Marc Anthony

At first glance, it's hard to ignore the importance of the 2008 class, solely due to the Flacco/Rice pairing. But top to bottom, the 2011 class is really strong, given that the top two picks will be long-term contributors, with Brown and McPhee and Taylor all playing roles. And Anthony Allen, though no longer with the Ravens, was a valuable asset on special teams during the 2012 season.

So now it's on you guys again. Which class is the best one?
