Andre Ward vs. Thomas Oosthuizen who wins? Should this fight happen on June 20, 2015?

With Andre Ward slated to make his highly anticipated return to the ring on June 20, 2015 part of Jay-Z's Throne Boxing on a TBA network the names I've been hearing as potential foes for Andre Ward are Marco Antonio Periban and Ricardo Mayorga all due respect Ricardo Mayorga is way past his prime this is not 2003 and if you watched James DeGale v Marco Antonio Periban recently he shouldn't even be taken into consideration. If I were to promoted a good Throne Boxing card and give Andre Ward the tune fight he needs in preparation for high profile fights the name I would go with would be Thomas "Tommy Gunn" Oosthuizen who has appeared on HBO he had that controversial prospect contest with Brandon Gonzalez back in June of 2013. Most important he is an undefeated fighter who has never been stopped and he is also promoted by Lou DiBella of DiBella Entertainment what you all think of this potential match up? Who wins this fight? Somebody should be reaching out to Jay Z and persuade him to promote this match.
