Very interesting match up. Davis can't use his wrestling because of Vinny's BJJ, but Phil's striking is pretty bad. All he has going for him is body and leg kicks, which could ultimately lead to a takedown for Vinny.
I think they'll end up in an awkward scramble, similar to Samman vs Casey, and Vinny will snatch an arm.
EDIT: Nevermind. I've been watching a few of Vinny's fights and his ground game in MMA honestly isn't that good. Yea, he usually gets the submission but it takes him forever. He'll get mount but not do anything with it sometimes.
I don't know how Phil will win, since his striking is poor and he can't use his wrestling, but I think he'll pull it off somehow. Hopefully I'm wrong.
Will make predictions for credits. Please, I'm so broke.
