Listen, I love the guy, but Dareus has a history of dogging it. I hope he's beyond those days (which were actually quite a while ago), but I'd be worried of how he plays after hitting the jackpot. It happens too often.
As for picking between Hughes and Dareus, regardless of play on the field (because they're both great contributors), you pick the guy who's still going to play lights-out after the payday.
