Why does Zab not have the mentaliy for the Elite level?

[ELPacman]

He seems to have the skills right? I can never see him beating an elite opponent these days when his mentality to win a fight just isn't there. He lacks to throw and his boxing skills are overrated. If he's not dominating by landing his big bombs to keep his opponents going back, he simply can't win. He gets fusturated easy and once he realizes he can't hurt or really intimidate his opponent, he gives up fast. Do you think Zab could ever win against the elite anymore when his mind seems to be messed up ever since his Kostya defeat? It's a shame because he has the tools, just can't apply them.

He lacks chin.

He is just starting to learn about heart.

He lacks consistency.

My thoughts are that he is bi-polar.
He has not fully matured.
It's not his fault. Something in his genes.
He should see a doctor.
He has trouble focusing.
He might have A.D.D
