The Ultimate Fighting Championship returns to Atlantic City, New Jersey, for UFC Fight Night 128 with another 155-pound showcase. Lightweight is the consensus best, deepest division in mixed martial arts, so it’s no surprise that it would be the centerpiece of three straight weekends. But as my colleague Pressley Nietering astutely noted this week, what exactly lightweight contenders Edson Barboza and Kevin Lee are contending for is unclear. Still, the pair provide a fun, intriguing, relevant matchup showcasing the highest level of the sport. That is not nothing. They might not be household names, but show a casual fan 30 seconds of a Barboza highlight reel or Lee swaggering and jawing, and he or she will quickly find reason to care.
