Derozan will end up better than Granger.
Ross will end up worse than George.
JV will end up slightly better than Hibbert
Lowry = West
Hill's current contribution = Amir's current contribution (eh, this is one I'm not too sure about)
DD can't become a non-factor like Granger has and hopefully avoids any career threatening injuries.
Then we still have this years draft pick, and a SAC 2nd rounder. We need to score someone that contributes. We should be able to get one borderline starter.
And we have cap room in 2015 to add a good player if we don't stumble into a Stephenson before then.
Obviously this couldn't be further from being a sure thing. But it's not so implausible as to be foolish to wait and see.
