3 years is a mighty long time.
I hope they all break out and become what we want them to be and they all take a discount to stay in Charlotte, but there's also a chance none of them take a big step.
...but that's not what you're after is it?
I'll go with Kemba & Smack, with a good possibility of Hendo & Mullens (the former has to get consistent and show he's not injury prone...the latter that he can be a man in the paint). The rest are probably close to if not at their highest potential or have negatives I doubt they'll overcome.
So I voted those 4.
