Many people thought that. Before the Estrada fight I fought the same. Then I was very disappointed after that fight that Adamek didnt KO Jason. Also I realized that Adamek will not be knocking out boxers in the HW. Its not because he doesnt have the power to do it (however his power at HW is only decent). Its because he wants to win the fight, and despite boxers like Klitschkos, he may outbox every other fighter in the division. Why taking the unnecessary risk, when you are ahead on the scorecards? Of course, when there is a proper moment - his opponent is tired or hurt, he may try and I believe he will try. Mike Grant was boxing very safety at the beginning, looking for a counterpunch with his right hand. When he hurt Adamek, he started being more aggressive, but didnt have the stamina to make a pressure for the whole fight.
