I don't beleive that Frank was dumb for standing.
I beleive that once Frank was in the cage with Cung, the way he didn't push the pace or close the distance was really dumb.
He was putting on a show, he was joking and throwing a kick and than backing up into the center of the cage again.
He was not aggressive enough for Cung. I still beleive that his stand up is worthy of Cung if he didn't screw around with those antics.
He came to put on a show, not to fight. That was his dumb move.
The only 2 real fighters that will destroy Frank at MW are Silva and Vitor if he live up to his potential (which will probably never happen).
I don't see why anyone would give Robbie this fight, it's not like Franks chin is suspect.
