well Silva walks around at over 200 Pounds and Aldo is around 160. Size means much more in mma than in boxing.
they prolly meet every day cuz they are team mates but if it all went down i would go to silvas side cuz i give him the edge in standup and he is a bigger dude
They are both under blackhouse mma but they don't train together daily. Anderson trains at Team Nogeuria and Aldo is out of Nova Uniao.
