How good is Felix Sturm and post videos of him in your answer?

Felix Sturm is mostly known for his controversial loss to Oscar De lahoya but now he is becoming a major part of the middleweight seen. Kelly pavlik is the champion but Arthur Abraham holding the IBF titles is everything as good as pavlik with power and a sturdy chin, a fight between abraham and pavlik was highly touted but after hopkins decisively beat pavlik he will need to get his legs back. Now a fight between Abraham and Sturm is being talked about(uming Abraham gets by journeyman Raul Marquez) he is a big runner to fight Sturm. If this were to happen i have no idea how good Sturm is if you find and videos of him against Sylvester or even Oscar post them and in your opinon who would win Abraham or Sturm?
