Manny Harris in the NBA?

As a casual basketball fan, I have a question for you experts: How do you envision Manny Harris' future in terms of the NBA? I watch him and agree with everyone that he's a great college player, but I have a hard time seeing him as an NBA player, at least not one in a big role. My opinion is only that of a casual fan, so I don't put much stock in it myself, and if I'm wrong, I suspect it is for one of two reasons. Either he's better than I think he is or he's projected to improve greatly, more than I would have thought. My take is that while he's a good slasher, he doesn't necessarily have the size for that to translate to the NBA effectively. And while he has a good jumpshot, his decision-making is poor, which will only be magnified in the NBA, where defense is much better. Further, is his 3-point shooting good enough? I know that he has other aspects of his game that help him out though (i.e. a good rebounder for his size and a good free-throw shooter). Again, basketball is not really my sport, so I make no claims to expertise. I'm just curious what others think and how far off my take is.
