My opinion is that the next Fox card will see a boost in ratings if its well placed and features fights that deliver. The last card was pretty exciting (despite that the main event was just a five round one sided beating) and people are discussing it much more commonly than events 2-4.
we already saw a boost, ufc on fox 5 (bendo vs diaz) did 4.4 w/ a peak of like 5.6! This article was written before then!
