There is a reason bookie gives you 4.33 for decision, Broe. Garbrandt has 9 wins by KO and only 2 by decision. And when we take away the outlier of a performance vs Cruz, he didn't look impressive over old and unathletic Briones. Or in the Brimage fight, until that knockout. He's not a round winner, he can't control the distance or the pace of the fight, which is essential if you wanna win decisions. If he had giant athletic advantage or wrestling advantage it would be different. He can't stay on the outside and win decision like Sandhagen, not against Assuncao. KO or bust.
All in for a guy who's already a favourite and he's not exactly fighting a can is not too wise. I'll steal a comment under the video UFC top finishes: Magny Magny is a mid-level boss fight in the UFC, massive stepping stone. You better come prepared. Your average welterweight doesn't beat Magny. It's usually a guy with a very special toolset, or some A-level athlete who can just overwhelm him with power. Rocco is neighter, but he's still very good fighter. All I'm saying is I like Magny, but I like him more as an underdog or at pick em at least.
