First off, congratulations to Chag. It is not an exaggeration to say that he re-vitalized his career with one punch. Look at all the threads that have been started about him! People want to see him against Huck, Wilder, Haye, and in re-matches with Wlad and Povetkin. Good show man. Now, who was #2? Gerber? Wallisch? Davteav? Dimintrenko? Schwartz? Poll will be up shortly. Please vote and describe.
Dimitrenko fought a total can. Zoltan Csala is a sideshow. Wallisch didn't exactly bowl over a contender himself or anything, but he looked the best of the bunch. His execution wasn't flawless, but there is definitely potential there.
Say what you will about Wallisch, he is a big boned super heavy who occasionally takes on other undefeated fighters. He needs to fight more consistently, though.
