The 2015 NFL draft was a great success for many teams seeking to improve their rosters.
One strong draft class can lead to an immediate turnaround and even sustained success thereafter. Just ask the Seattle Seahawks after they hauled in a tremendous crop of talent in 2012. Seattle hasn't missed the playoffs since, has won a Super Bowl and played in another.
A lot of that can be attributed to the Seahawks finding a franchise quarterback in Russell Wilson in the third round.
Bottom line: No pick can be taken for granted.
