Do you like the new trend of football teams relying on two backs rather than one running back now?

It appears that over the past few years teams have gone with a 1-2 punch of two backs. A great example would be the Giants and their use of Ward and Jacobs. The Dolphins are another good example. I still remember when teams would use one running back and make him a workhorse. Guys like Walter Payton, Emmitt Smith, Eric erson, etc. It seems like teams are using their backs to catch a lot more pes now too. A good example of that would be Westbrook with the Eagles or Reggie Bush with the Saints. Do you like this latest trend where teams have two backs to share the running workload and they are used to catch pes too or do you like the old school use of backs?
