it's nonsense without context. with context, it's just another tool.
What is a successful dribble anyway? Is it beating a man?
From the stats, we can't tell if Fernandinho is simply getting the ball kicking it 10 yards in front of him and using his powerful acceleration (I have no idea if he's fast) to beat his man, which depending on where he plays in midfield, might not be the most defensive opponent.
On the other hand, he could be a Ronaldinho-esque dribbler and he uses his wide array of skills to beat his opponent.
You can't tell from the stats. There are a lot of powerful footballers on the Premier League best dribbler list, and not an awful lot of the footballers you'd normally associate with being the best dribblers.
Looking at the list of the most successful Premier League dribblers, players of West African origin appear to be more represented than they are in the Premier League as a whole. West Africans typically have more fast-twitch muscle fibers, allowing for powerful acceleration, which is why pretty much all the great sprinters can trace their heritage back to Western Africa. It doesn't make Samba Diakiete or Chiek Tiote a great dribbler.
Stats can be a useful supplement to actually watching matches, but you can't tell anything from reading about how many DPGs (dribbles per game) Ferdandinho had.
