Huh? I went back and rewatched rd 1 of Silva vs Shara Bullet just to make sure I wasn't remembering totally wrong...but no clue why you'd say he looked bad early in that fight. He stalked Shara more of the round than not, landed some big shots, and it was a super competitive round. If he lands those shots on Weidman it's likely over, Shara ate them but I'm guessing his chin is a wee bit better than Chris's at this point.
Chris needs to get his wrestling going early to have a shot imo. If he stands with Bruno he's likely getting KO'd. I just don't know if Chris has the explosiveness to hit TD's anymore.
@Stat_Collector did make a good point about OSP though. I thought he was beyond washed and grabbing one last paycheck but he showed he still has heart and still was fighting to win so I guess we never truly know.
