Traits you want in an RB3
Now that you know what an RB3 is in fantasy football you may be wondering what traits you want to look for in these players.
Potential to climb the depth chart
One thing that fantasy managers want out of their RB3 is the ability to climb the depth chart. Since these players are ranked from 25 to 36 it is common for them to not be the starting running back on their team.
Having a chance to gain that starting role throughout the season is going to make the ceiling of these running backs much higher.
Whether it is due to injury or poor play passing the top running on the depth chart can pay off huge dividends.
Fantasy managers should look for younger RB3s if they want a shot at taking over the role of starting running back in their offense.
Ability to score on limited touches
Another key factor that you want to look for when getting an RB3 is the ability to produce when not getting a large number of touches.
RB3s as a whole tend to get significantly fewer touches than RB1s and RB2s. This is because these players are either not the starter or they are on a team that doesn’t run the ball very often.
In these situations, you want a player that can break off a big play or remain productive on a limited number of touches.
This way you will not be waiting for the opportunities to improve for your running back but will instead be able to produce fantasy points despite your player not seeing a large number of snaps.
