It takes years to gain the perspective necessary to fully judge a draft class in the NFL. Teams select players based on long-term outlook, and often their potential isn't immediately apparent as a rookie.
Still, for a team like the Green Bay Packers, getting first-year contributions is important. Their Super Bowl run in 2010 likely doesn't happen without Bryan Bulaga stepping in for the injured right tackle Mark Tauscher or Andrew Quarless filling the void left by tight end Jermichael Finley. Likewise, the franchise doesn't appear in the NFC Championship Game in 2014 without the steady play of safety Ha Ha Clinton-Dix or center Corey Linsley.
