college bball isn't my strong suit (I've simply been too busy the past 3 years to give it much attention), but I'm guessing Rivers will be a guy that drifts steadily upward in the mocks. In other words, if we have two picks, I wouldn't count on him being available for the second. Just a hunch.
I think you're right. The NBA scouts that I have spoken to seem much higher on him than the mocksters are.
