If Miranda faces Ward, then Bute-Inkin is one of the only fights that would make sense for Bute. Not sure who Andrade would face, but there are plenty of guys he could face in a stay busy fight on the undercard. He doesn't need to fight a ranked opponent. Dirrell's going to be named Balszay's mandatory at some point, and that's a MUCH more winnable fight for Dirrell than Bute is, so I doubt Dirrell would give that up to fight Bute.
If Miranda-Ward is true, then the only available fighters in the IBF top 15 are Bika (an option, but the first contest was lopsided for Bute), Brinkley, Inkin and Dirrell (not going to fight Bute for the reasons set forth before).
I didn't like Andrade the first few times I watched him because of his style, but he's just such a hard person to dislike, and frankly he's made huge strides with his actual boxing since the Kessler fight. There were a lot of punches he was slipping last night that would have nailed him square on the chin against Kessler.
