The reason I doubt Thompson a little bit is that Thompson wasn't as good as Raymond Daniels or MVP - but Daniel's got tooled against good kickboxers.
Other wise, I'm glad at the points made by NAKMUAY18 - guys like Max Holloway are great strikers by any standard. I've been saying for a little while that MMA striking is now at a point where it's pretty good in general. I don't think they're as good as kickboxers, because they're not, but being real here, if I put Donald Cerrone against most kickboxers (save the elite) I think he has a good running against most of them. I could legitimately see him beating a lot of the top american and british kickboxers... probably not the dutch and thai though
