He is fighting with 20 extra pounds though. Another reason i have is i dont see Jan getting the KO although highly possible. Bisping did KO Rockhold after all but Jan Himself can take some shots, Only KO'd by Thiago Santos and some other dude, i see Jan taking a UD.
On Thiago who also moved up and did very well at 205 I just think he is another kind of level then Luke but i have been wrong just my opinion.
I really think he just didn't respect michael at all but who knows we'll see
