[header] How to be a running back [title] Decide what type of back you are. [step] Are you an elusive back? Or a power back? Now every back has their advantages and disadvantages. For example a power back will be able to break tackles much easier than an elusive back but an elusive back will be less likely to get hit and run a fair amount faster than a power back. 
Your body and natural abilities should help influence your choice. If you are naturally fast an elusive back would be best for you but if you find you're strong and powerful the power back might be your best choice.
