Yeah, Hathaway's looked pretty tame since Mike Pyle destroyed him in 2010.
I'd personally like Hardy vs Riddle. Dan's just come off a 4 fight losing streak, and one win against Sadollah shouldn't bump him up to Koscheck's level. It'd also more than likely end in a defeat. I'm a huge Hardy fan, but he's still not ready for an elite wrestler, especially one like Koscheck. He'd be wise to take the Riddle fight, take him out, and then think about someone at the higher end of the division. He has been calling Koscheck out for years though, so it doesn't surprise me to see him call him out again.
