Miami selected 10th in the 3rd round and recognized the need for a running back selecting Kenyan Drake of Alabama. A combination of speed and size, Drake can return kicks which is something that he will likely do to start things off with the Dolphins.
Drake is a very fast runner who can explode into open space and then becomes a dangerous game breaking back. Another benefit for the Dolphins is that Drake is capable of catching passes out of the backfield and can split out from behind the quarterback. Drake is not only fast but he is quick and yes there is a difference.
