Here is a top 5 list that came up when I googled biggest robberies in MMA
5. Nam Phan vs Leonard Garcia
Striking favoured Pham 174-100
Phan outstruck him in each round
4. Edgar vs Maynard II(I disagree that this was a robbery)
Striking 95-71 for Frankie.
Frankie outstruck him in each round after the first.
2. Lyoto vs Shogun 1
Shogun outstruck him 80-35 in sig strikes, 82-39 total. Shogun outstruck him in every single round.
1. Diego vs Ross Pearson
Pearson outstruck him 51-33 and outlanded him each round.
In each of these the "Robbed" fighter outlanded their opponent in the entirety and in the majority of rounds.
GSP vs Hendricks is listed as #3
GSP out landed Hendricks 101-85 in significant strikes. But Johnny was robbed.
GSP out landed Hendricks 142-125 total strikes. But Johnny was robbed.
GSP out landed Hendricks 31-15 in the 3rd. But Johnny was robbed.
GSP out landed Hendricks 9-4 in the 5th with 2 TDs to none. But Johnny was robbed.
GSP outlanded Hendricks in Sig strikes in the first 19-18.
Hendricks out landed GSP in total strikes 27-26
Both fighters had 1 TD each.
GSP had the only submission attempt.
Literally a razor close round that could have gone either way. But Johnny was robbed.
Note how this "Robbery" is statistically opposite of the other 4 in the top 5? It simply is not a robbery. The night of the fight Johnny got "The Halo Effect" in many fans eyes. This is one case of MMA judges actually being competent and the statistics bear that out.
If you have an argument besides "But its on a list", perhaps with some facts to back it up I am listening. From where I saw it rounds 2 & 4 were Johnny's and 3 & 5 were GSPs. I scored the first for GSP. If you scored the first for Johnny I can see that. If you want to argue how it wasn't remotely close in the first I am all ears. You can think Johnny won but it was not a robbery.
