Let's put some things in perspective:
The KO/Zeller front court played and excelled against Toronto against Patrick Patterson and Tyler Hansborough and Sully played almost all his minutes that game versus Amir Johnson and Jonas Valunciunas The KO/Tyler frontcourt then played well versus the frontcourt of the Sixers that was Henry Sims and Brandon Davies. Heck that entire team of players that played for the Sixers that night probably shouldn't be playing in the NBA.
Basing an opinion on the KO/Zeller frontcourt on those games against that competition is patently absurd and ridiculously pre-mature.
Also, keeping things in reality if we want to discuss defensive stats of Sully versus Olynyk let's use last year's stats where the games counted and coaches and players were actually trying to win games and not this pre-season. In those stats Sully had the lower defensive rating, the higher defensive rebounding percentage, the better +/-, the better modified +/-, and the higher number of blocks Per 36. He also drew way more charges and the eye test showed he was the superior defender by a wide margin.
Both players look much more comfortable in the system this year but until the games count and they are playing real competition, basing anything on what we are seeing this pre-season is a bit preposterous.
The best frontcourt thus far this season has been Sully at the 4 and Olynyk at the 5. And its not even close.
good points and data nick. what you write does indeed match my "eye test" evaluation of olly and sully. i like olly's offensive game, but on defense it is not contest under the basket. sully is like rock, immovable and determined on rebounds.
i think this year for stevens will be a combo of player development and set development. by set development i mean that stevens will put out particular sets of players (e.g. olly/zeller, olly/sully, turner/bradley, etc.) and see which set plays best under which circumstances.
if so, then i think we will see plenty of olly/zeller set until it shows it doesn work. but so far, sully and olly look the best as a pair. their skills compliment one another.
a set i would like to see would be zeller at center and green at pf. interesting inside/out combo there.
