Do you think Koufos could be our starting center going forward? Or would he be just a stop gap? In general I would prefer future assets to an expiring contract for Green, but if Kosta could take over at the 5 then we would probably re-sign him.
I don't think Koufos is anything more than a stop-gap option as starting center. Backup center is correct role for Koufos.
Koufos is too limited as an overall player to be a permanent starter. His offensive game is limited to shots around the basket. Garbage man. Non-passer. His defense and rebounding are solid but nothing spectacular.
Lack of high level physical gifts (in any and all areas) limits utility as defender + rebounding. Lacks physical strength to be top post defender like Perk was. Lacks top quickness and mobility to cover quicker face up bigs or to provide top team defense (PnR, transition, speed of defensive rotations). Lack of great length or leaping ability as shot-blocker. Average physical size for center (unlike slow centers like M.Gasol, R.Hibbert). A lot of mediocre physical tools that make it difficult for Koufos to
physically matchup against the top players & athletes that start at the center position. Without the offensive skill-set to make up for that, Koufos is best used as a bench player. Steady enough player to interim starting center until someone better comes along but bench player is right role for him.
I don't think he is worth giving up Jeff Green for.
