Wow, really surprised most itt are on RDA. He has resorted to a completely clinch/td/grappling based gameplan at WW thus far and has had good matchups to do so. When is the last time Lawler got grinded out in the clinch? I think the size/strength/power here will be too much in a contest that will play out mostly on the feet. Hendricks and Condit both hurt Lawler at points in their fights to arguably win rounds, RDA didn't carry much power at LW, so it seems very unlikely he has that option. Cerrone hit Lawler with some flush clinch elbows and a headkick and he seemed unfazed. The year off was great career management for Lawler and now hes back training with beasts like Usman everyday, who happens to be a great training partner for RDA with his pressure and clinch based game. For RDA to win he has to outvolume Lawler for 3/5 rounds without getting caught, while also relying on the judges not scoring Lawler's more powerful shots with more emphasis than his volume. Lawler around -200 seems more accurate IMO.
Edit: Another important point to consider.....one of RDA's best weapons is his left body/liver kick, which will be negated here due to it being Southpaw/Southpaw.
