HOUSTON -- We're going DeAndre Hopkins heavy because his (expected) emergence is a very important factor for the Texans' offense.

Rookie receivers don't always produce right away. It takes time for them to learn the systems they're in. It takes time for them to adjust to the NFL game and NFL coverages. That's why Hopkins' total of 183 yards for his first two games is the most by any rookie receiver since DeSean Jackson and Eddie Royal in 2008, according to the good people at ESPN Stats & Info.

Jackson finished his rookie season with the Philadelphia Eagles with 912 yards. That season foreshadowed big numbers in his career. He had two 1,000-yard seasons immediately following and his average per catch has been better in every year than it was his rookie year.

Royal, now with the San Diego Chargers, caught three passes for 24 yards and two touchdowns in Week 1 against the Texans. He started his career with the Denver Broncos and caught 91 passes for 980 yards his rookie year. After that his production dropped significantly due in large part to a coaching change. Royal also had hip surgery in 2011.

What does this mean? Early success is difficult and can predict future success barring injury or unsettled management.
