Its his damn management under Klaus Peter Kohl...I think Sturm could and would step it up,but as long as Kohl(and to be fair also Sturm) can make money with letting Sturm fighting no names(that doesn't automatically mean they are bums though)nothing much won't change...The same happens with Erdei,Dzinziruk and will happen to Arslan(cruiser) and probably Chagaev...

The Klitschkos were also under Kohl management and as soon as they could they got out off their contract even though that probably had more to do with money issues than the quality of opponents,but still...

The only promoter(and manager)right now seated in Germany and willing to let his boxers fight anyone is Ahmet Oehner(even though he is a jackass)...
