Huh?
How does Johnny Walker's fate have anything to do with Alex Pereira?
Oh, is it because your ape-brain only sees the fact that they're both "tall Brazilians?"
In reality, the two are light leagues different in skill, aptitudes, experience, and success.
Johnny Walker = constant failure at the top. Virtually zero skill, just reflexes and power.
Alex Pereira = constant Champion at the top, now in two completely different fighting organizations. Master tactician, professional poise + strategy, matched with crazy power.
