Probably?!? He would've made Rashad look really really bad before putting him down.
The only LHW in history that would be favored over a Peak Anderson would be Jones.
Anderson who was a decade past his prime, with a weeks notice coming off surgery still went the distance against 2016 DC, the same guy who would submit Rumble for the 2nd time his very next fight.
Anderson is actually underrated by a large portion of the MMA community, Rashad would've gotten blasted, started talking trash instead of shooting for takedowns and would've eventually gone out on his shield in devastating fashion. It wouldn't even be close at all...
