Top rookies for dynasty leagues

The 2014 NFL draft is in the books, with 256 players having gone off the board. While there is a lot to consider in terms of fit and situation, as well as looking at how players perform in training camp and the preseason, now is as good a time as any to examine potential fantasy impact.

When putting together a dynasty ranking for fantasy football, it's important to think about the big picture and positional value. For example, finding starting-caliber (for fantasy reasons) running backs is much more difficult than finding quarterbacks to start on a weekly basis. And while obviously success this year is important, owners should keep an eye on each rookie's long-term value beyond 2014.

Assuming a standard format, this is how I value the incoming class of rookies for dynasty leagues:

1. Sammy Watkins, WR, Buffalo Bills

Watkins is a great wide receiver prospect. He doesn't have ideal height (6-foot-1) like an A.J. Green or Julio Jones, but he does have everything else you look for. Even as a rookie, he should be an every-week fantasy starter and shouldn't take too long to develop into much more. That is, unless QB EJ Manuel holds him back.
