Ok back to your question id take Darius. Collins was tough had a lot of heart and had above average skills, average puncher,but he would be outgunned here Darius hit a lot harder,bigger,and just a better fighter. Collins was tough though and i dont think Darius would knock him out. Collins would be competetive but Darius would put it on him and win a convincing decision. 117-112 Michalczewski.
Would go with Dariusz in a bit of a tough fight, he is technically better and puts his punches together better but Collins would make him fight for 12rounds
