Agreed with above. Olynyk is an offensive force. Superb passer and improving shooter. His defense is not of high caliber physically, but position wise is quite good.
If Olynyk is a bench player working the perimeter for shots, he is best used.
Sully is great, but, can lose ground when required to play center against good bigs. He should be a real legit NBA PF as soon as management gets us a centah.
Don't see the "two rookies" as a full time front court combo.
