Ring had Trinidad p4p no. 2 before he faced Hopkins. Oscar was p4p #4 after his second loss to Mosley, but for me his "win" against Sturm put him out of p4p top10 for sure. So I don't think he was p4p top10 at the time. Winky was no. 3 at the end of 2006, before he faced Hopkins. For me, the fight of Hopkins and Wright was also underrated, it was the fight of two p4p top 5 fighters, which does not happen that often. I had their fight even.
I believe Trinidad was number #2. Oscar was rated #4 Winky was rated at #3 All ratings by the Ring http://boxrec.com/media/index.php/The_Ring_Magazine's_Annual_Ratings Pretty impressive for Mr.Hopkins, but then again 2 out of those 3 fighters face him at higher weights.
