As you might expect, higher draft picks have more productive careers than lower draft picks. Still, have you ever wondered by how much? Pro-football-reference.com has developed a proprietary statistic which can answer that exact question. Called Weighted Career Approximate Value (WCAV), it can be used to compare the overall production of different players. In this post, I use WCAV to evaluate the career of 1999 #5 overall pick Ricky Williams.
