For most NFL rookies, the first year in the league is all about learning and developing. For those taken on Day 1 (and some early in Day 2), there's a lot more to their rookie season.
Early draft picks are held to a higher standard. It doesn't take long after a quiet or disappointing first season for fans and analysts to start having questions about a rookie's future.
Patience can be rewarded when it comes to NFL player development, though. The reality is that rookie contracts are typically four years for a reason. It can take a while to see a player fully develop.
