Hopkins facing Cleverly makes the most sense.

[SirTomJones]

Cleverly isn't a draw, his world title fight was the undercard fight for Degale Vs Groves.

He could sell 20k in Cardiff.

that fight would have to be in the UK to do well and with Hopkins being the Champion, other then maybe fighting in Canada again, I serious doubt he is going to travel...especially for someone like Cleverly

Cleverly would be a much easier fight for Hopkins though IMO just based on STYLE
