Just went and re-watch the fight.
For round 1, Edgar took the octagon control by moving forward but Aldo probably did more damage and out-strike him. 10-9 for Aldo.
Round 2, Edgar arguably took the octagon control aspect again but Aldo significantly did more damage especially with those leg kick and take a convincingly 10-9 round.
Round 3, Edgar score a takedown and mange to out strike Aldo (although not far off) on feet. But Aldo strikes seems that it did more damage. Depending on what the judges are looking for. 10-9 for Edgar for out Striking or 10-9 for Aldo for damage.
Round 4 is all Edgar. out matching, striking and and big takedown. 10-9 for Edgar.
Round 5, Edgar still outstrike Aldo but Aldo did land a few good shot. Still 10-9 for Edgar.
It really depends on how round 3 goes. Initially, I gave round 3 to Edgar but after re-watching it, I gave it to Aldo.
No complaints that Aldo won this close fight right here.
