re: Is Orgeron as HC hindering Aranda’s future?

No.

If anything, the instability of the last couple years factored in to LSU stepping up to make Aranda one of the highest paid (maybe highest now?) assistant coaches in the country. Aranda is highly valued, and he's likely richer for it under Orgeron than he might've been if Les were still here.

And if Aranda wants to leave, he will easily find another high level job (though he's so well paid, it might be a pay cut unless it's an HC job... and even then it might be a pay cut).
