Amanda fucked Cats shit up something fierce in that first round. Cat went limp at one point too. Amanda also brutally TKOd Germaine in the 1st and 9/12 wins were finished in the 1st.
Amanda is like Vitor or Rumble in that early storm you have to weather. She just pushes such a high pace and has the abilities to completely control the pace, it takes a special fighter to be able to win the 1st against her. To weather that storm is no easy task but Miesha is one of the toughest girls in MMA history, but she has a huge hole in her striking and Amanda is dangerous everywhere from kicking range (finishes Shaina in the 1st with leg kicks), boxing range (dropped Mcmann with a punch to set up the sub) and clinch (destroyed Cat early there).
Amanda has Vitor/Rumble syndrome tho in that if u can fight control of that pace and have enough offensive output they fold and quit. Miesha can do the same but i could see her getting finished early too.
