The second round of the 2012 NFL Draft was hit or miss with the majority of the players selected. Teams such as the St. Louis Rams missed with Appalachian State wide receiver Brian Quick but hit with former Florida cornerback Janoris Jenkins.

Logic tells us that's it too early to decide which picks were slam dunks and which were busts.

But we can evaluate how they did during their inaugural rookie campaign to see how much of an immediate impact they had on their squads.

The most effective rookies from the second round include: Cleveland's Mitchell Schwartz, St.Louis' cornerback Janoris Jenkins, Buffalo's Cordy Glenn, Kansas City's Jeff Allen, Seattle's Bobby Wagner, Tennessee's Zach Brown, Tampa Bay's Lavonte David, Baltimore's Kelechi Osemele, and Green Bay's cornerback Casey Heyward.
