I'm 99% positive the winner will fight Floyd next. Simple lack of opponents / big names.
Pac, Bradley, Marquez with top rank so cross them off the list.
Keith Thurman just isnt there yet.
Devon Alexander actually would be a solid opponent, but I just dont think the powers that be would want him headlining a PPV against Floyd (because it would be a tough sell).
Amir Khan would be a very big name, but he's looked bad recently.
The rest of the 154 pound guys just dont have a name - Lara, Trout, etc.
So really that only leaves Matthysse/Garcia.
