The future is fluid and unpredictable. It's like trying to capture running water with your hands. You can't see it. You can't get into a machine and watch it fly by. The future does, however, leave clues.

In football, those clues are named Russell Wilson, Todd Gurley and Antonio Brown. The clues are franchises that draft wisely...and don't.

This chapter of Bleacher Report's special series ranks the franchises in terms of promise. Some teams rank well, while others could use a time machine.

We'll look at the top five young players on each team (under 30) as well as give a "Young Prospect Rating" where we are looking at the rest of the young players on the roster and their future outlook/productivity. These will be graded either Bleak, Solid, Good or Excellent.

This is the fourth of five chapters to determine the greatest NFL franchise in history. This is one of the more significant since it's about hope, and hope is the best part of being a fan, a player or a franchise. There is hope for all. Even the Cleveland Browns.
