A very harsh thread on Khan. Looking at 147 Id give him a decent chance of beating all of them. Below are fight news rankings with the chance I give Khan of winning

1. Keith Thurman 40%
2. Kell Brook 33%
3. Danny Garcia 60%
4. Timothy Bradley 50%
5. Jessie Vargas 70%
6. Shawn Porter 40%
7. Errol Spence 25%

Considering most of the time these guys fight they are the 90% fav or bigger Id say Khan is very relevant
