My impression is that Rios has issues with Ortiz but I can't figure out what it's over. When ever he's asked about it he gives a "he knows what he did" response. It also seemes that when ever there is a video of Rios and his trainer Robert Garcia together, they both seem like dickheads. Garcia is a very good trainer, but he still comes across like a dickhead.
There's a video on youtube of Robert Garcia's nephew, featherweight prospect Miguel Garcia, talking about the beef. He claims it has something to do with a fight Victor and Brandon got into, and Victor basically didn't back Brandon up. In reality, it might be more to do with the fact that Victor and Brandon were both training with Robert Garcia, but Ortiz left to train with Robert's brother Danny Garcia.
