When Wladimir Klitschko fights this weekend, you will be seeing the same Klitschko you have seen for the past six years.
If you are fairly new to boxing, this wasn't how he always fought. It took some losses and a new trainer to get to this point.
Fighters have been changing their style since the start of time. A change of style may happen for a plethora of reasons.
It may for the better of the fighter as in the case of Klitschko and Marco Antonio Barrera. Sometimes a fighter just gets older and needs to make the change.
In the very unfortunate cases of some, their styles are altered by the death of an opponent. Changing trainers could be a reason that a fighter decides it is time to change their ways.
Whatever the reason may be, some fighters have changed their styles and it will always happen. The real question is, was it for better or for worse?
