Actually when Ells does get picked it is the same way every single time. He does not go back to the bag the same way every time. When he feels like he does not have to rush back, he uses that stupid crow hop. Then the first and only time he is forced to crossover step...WHAT A SHOCK...he looses his balance and his footing and can't make it back.
If you were to go back and watch film of the guys the sort of invented modern base stealing, none of them uses that stupid crow hop. They go back to the bag the same way every time.....crossing over. Then when they really have to move to get back, all they have to do is crossover faster.
