I wouldn't think Davila was completely "out of his depth," but I'd still expect Rose to win it in the end. I'd say Davila matches up with Rose similar to how Rudkin did.
I think Rose wins a wide decision. If he's as focused for this as he was for Harada, he shouldn't have anything to worry about IMO.
I think Davila makes it very competitive in the first half of the fight until Rose starts to take over and outpoints him in a great chess match.
