The main event at UFC 159 is Jon Jones' to lose.
His challenger, Chael Sonnen, is a gritty competitor with tremendous wrestling skills. Jones can match those wrestling skills, but what he has that Sonnen doesn't is a diversified striking style.
Jones has the tools to keep the distance on Sonnen and batter him with shots from the outside. So on paper, Jones is easily considered the favorite in this bout.
That doesn't mean we don't have questions for the champion. Here are some questions we'd like to ask Jones before he heads into his championship bout against Sonnen tonight.
