I've watched Duke a handful of times this year and I think they have a very similar offense to ours. The huge differences from ours, however, are:
(1) Mason Plumlee is a very legitimate NPOY candidate who is extremely active moving without the ball and attacking the basket (Not to Mention Ryan Kelly who also is a big Forward and scorer). This is such a huge difference...Plumlee and Kelly vs. Rubles/Mbodj (or Jackson/Mbodj). It is no contest. That offense works well when you have bigs that move a ton and can successfully attack the basket, roll to the basket and most importantly, finish from 5 feet and in consistently.
(2) Although I love SK/Parker, Duke has multiple McDonald's All-Americans who inevitably handle the ball better, attack the basket better and can pass/dish. Basketball IQ is higher as well.
(3) Passing very quickly (which really is expedited by Duke getting into the paint more and getting the ball into Plumlee/Kelly and other bigs much more often than we do)
I think Duke shows what the offense is when run very very well. For us though...With only 3 guards that are only pretty good at creating their own shot, and no real post-presence or option for a big consistently to score, I do think it is a difficult offense to run.
That said, I think we took some steps forward in the past two games (since the St. John's one), and I do think as Rubles, Sanders, Shaq improve, that will help. Obviously, we won't be Duke.
I really do wish we just had an Option B on offense. When the other team is in man, it seems like it's all we have. I'd love an Option B offense where we set a ton of screens for SK, Parker and Cash, and our bigs were active in the paint.
