No doubt shooting is a weakness next year. Just one of many reasons why next year they won't be ready to contend (mostly Thad needs a few years to start to tap into his full potential.)
Fortunately, Thad, Iguodala, Lou, Smith, Speight can all shoot and are 20-24. I expect their jumpers to improve- even if none become truly automatic. We can add a great shooter or two next summer, and worst case can always move Iguodala or Miller in the next 1-2 years if it looks like Shooting will be the Achille's Heel- Ouch, not the best reference...
