Film matters. Analytics matter. College production matters. Draft capital and landing spot matter. The debate about which variable is most important or best at predicting future NFL and fantasy success will rage on. However, at the intersection of every variable we use and every lens through which we look to evaluate a prospect sits an individual, unique player.It doesn’t matter how predictive we think our research is. At the end of the day, a rookie and his coaching staff still have to go out and get the job done.When evaluating the long term dynasty potential of a rookie wide receiver, we have to work with what we have. Anyone who tells you they have all the answers is selling you something. However, certain historical trends, film analysis, and other variables can give us a glimpse into what is possible.As I attempt to breakdown the dynasty outlook of Marquise Brown, keep a few things in mind: we only know what we know. He has extremely limited professional experience and much of what will be covered is speculation that is, however, rooted in research. Will he do enough to provide fantasy relevance this year or in the future?
