I think it could. MM isn't tested as a draw yet, and Barao has already proven that he is not a draw.
If I only have $55 and had to choose one, I would buy 174. Course, I like MM better than Barao and I feel most of the match-ups in general are better on the 174 card.
We will see. I believe they both do terrible but 173 does a little less terrible, which is sad
