Me too. Ive watched his first 6 fights today. One of the things I noticed about his early opponents were that they were capable. Watch his pro debut opponent. He went on to have a poor record but the guy knew what he was doing. I don't mind that its when you see a top prospect against someone who doesen't have a clue.
actually he started out at light welterweight, for his 4th fight he went to 135 because top rank wanted him to pick up a title there but it was too hard to make the weight so immediately he went back to his normal weight the next fight.
They all vary because the fights are coming from different sources. Fights recorded in the modern HD era are going to have extremely high quality, virtually identical to the original broadcasts. However, a lot of the earlier fights (pre HD-DVR/DVD Recorder) are going have average to poor video quality because more often than not they are being transcribed to DVD from VHS. Though sometimes you can get high quality videos of much older fights after they've been replayed by a network in the modern era. Even more rarely, fights fans are sometimes able to get copies of fights from promotional companies in pristine condition. Most of these career sets you see being sold online are downloaded from Torrents/File Sharing sites and converted to DVD. I'd recommend downloading them yourself if you're even remotely computer savvy. It's not that hard to find them, nor is it that hard to convert them, though, it can be a little time consuming.
