Let’s look into the fact that most of the time, receivers do not come in and contribute in a big way early. Obviously, rapport and trust need to be built with the quarterback first, but how quickly is that earned?
There are very few rookie wideouts who go over 1000 yards in their first season. The thousand yard season is sort of a benchmark for most guys who would be called a #1 WR on their team. In fact, since 1970, there have only been 17 wide receivers who have gone over 1000 yards in their first season.
