This time of year, you'll often hear, "We need to draft an OLB in the 1st round, a safety in the 2nd, a WR in the 3rd, and a CB in the 4th." To begin, whatever players you draft may not be ready to start Week 1 of their rookie seasons, and if you're depending on a rookie to be a major factor in getting you to the Super Bowl, you probably don't have have much of a chance of getting there in the first place. But more importantly, by the time young players are in the NFL for 3 years and ideally they've developed into good starters, the roster is often going to look nothing like the way it did when those players were drafted, and you may have passed on a better player who plays a position that is a need in 2016, but wasn't in 2014.
