Far too often the UFC books title-bouts based on a string of semi-impressive showings, a competitor’s marketability, or simply desperation on the part of the promoters. For every “paper champion” there are a few “paper contenders” as well. For example, consider the number of opportunities Chael Sonnen received despite having lost convincingly in numerous clashes. Simply put, while they may all be talented fighters they aren’t necessarily legitimate threats when it comes to dethroning divisional kings. (Photos by USA Today Sports Images)
