Because Glover's 41-years-old. On a 5-fight win streak. Is now ranked as the top contender. He doesn't have much time. Give the shot to him now. If he wins then Glover vs Izzy is a more intriguing fight than Izzy vs Jan, as Glover's top game BJJ is top class. This means Glover has a more realistic chance to win than Jan with the power striking, imo. While if Jan wins he has a title defense. Makes him more legit and the Izzy and Jones fights get bigger. Izzy has options. Could try to get the Jones fight. Or could rematch Whittaker and move up after that. Whittaker has said he'll take that fight in March. Otherwise I think what will happen is Izzy beats Jan, then Jones challenges Izzy for the 205 belt. While Glover sits out a year or more. Or takes on one of these young LHW contenders, which is a big risk. For once they should think long-term.
