From a marketing standpoint, this scenario is a win-win.
A Sonnen-Silva rematch would be the most sought-after bout as Chael was the last man to truly challenge the champ. All reports have it that if Sonnen, who was in line for an immediate title rematch prior to a suspension for elevated testosterone levels, bests Brian Stann at UFC 136 in October, he will receive a much-desired second shot at dethroning Silva.
Brian Stann has skyrocketed into the spotlight in the past year after consecutive knockouts against Chris Leben and Jorge Santiago.
A solid resume and an ever-improving all-around game are only part of the picture. Stann's war-hero background, "All-American" appeal (pun intended), and his tendency to always say the right thing truly make Stann a promoters dream.
A rematch between Silva and Sonnen may not be expected to match the classic war of the first meeting, however it would be a very interesting matchup both because of the contrasting styles and because of Sonnen's past success.
