Augusto is not a boxer. He is an out fighter who wants to counter guys who chase after him, or strafe in on angles at stationary targets. Saying "he was afraid of being in the pocket with pendred" because of pendred's striking is a huge stretch, he obviously didn't want to clinch with the blanket wrestler.
Yes, Belal is great at cutting guys off, but he is -360 and got dropped multiple times by a power puncher as he stalked him down in his last fight.
There might be value in both montanos, they are separate fights, I haven't fully researched erick yet.
