The only question that matters is whether Ajinca and a player TBD can give you 75% of Asik's defense and 400% of his offense for 65% of his cost.
I feel like people are attached to Asik, and it really just comes down to value. Asik is fine on a short deal with a team option in the 3rd year, or a 4 yr deal at around $8m per. 4 years and $40+m for Asik is absolutely insane both because of the length and the cost.
