Who should Parker fight next?

It's clear the kid still needs a lot of seasoning, but who'd be the best option from the available heavyweights? Many pick Jennings, which I think is a sensible choice, though Jennings would probably have to nab a win beforehand to make the fight respectable. I've also heard Duhaupas's name being bandied about, which I don't think is a bad option either. Duhaupas is coming off a win against Helenius and has the sort of high pressure, tenacious style that could really test Parker's defence and stamina. Parker's team might not be so keen to throw him in with another guy like that straight off the Takam fight though. Who else? Szpilka might give him a bit of a puzzle to figure out, though I doubt his chin holds up for the full twelve. Pulev would be another tough option. Washington? Scott? Cunningham? Not sure if any of those guys test Parker in the areas he needs to desperately improve in. Dillian Whyte? Ha, maybe. My pick would be Jennings, if they can get him. Respectable fighter who'd give Parker a lot of rounds without posing a huge danger. Make it happen!
