No I would bet heavily on Trinidad in that matchup. I'd be taking out loans just to get a big wager in. Trinidad was very strong @54.
Vargas @54. He had pretty quick hands but he is also there to be hit in return. To your point Trinidad got knocked down usually they were flash KDs. He wasn't easy guy to take out.
He had some mobility? That would.be the best way to approach it. Did Boudouani face guys on that same level and have success? I only vaguely remember him. Trinidad keep the pressure on for 12 rounds. He had uncommon stamina and he carried his punch late. When a guy moves that much they get tired just like Oscar.
