fantasy football rankings: Top 20 RBs for 2015

Perhaps you've overlooked this, but fantasy football draft season is almost upon us -- but don't worry, we've got you covered.

Tuesday, we dropped our quarterback rankings for the upcoming season. Today, we give you our rundown of running backs -- the most crucial position on your squad, but the trickiest to nail down.

Even the top few spots aren't easy to put in order, unlike in years past. But we tried to make sense of the running back pack for your draft preparation needs. Click through the rankings above, and be sure to keep an eye out for more positional breakdowns from AOL Sports.
