I especially like Afflalo has a player, but he seriously needs another year. He has a leadership-type mentality, good scoring/shooting ability and a potential two-way skill set, but there are many players like him in the NBA already, and if he can show some new aspect of his game (more drives to the basket, better passing ability, etc.) that would make him even more versatile and even more of a commodity for the NBA. Of course, he's had a drastic improvement from his freshman to sophomore year, and has hence raised his stock to bubble first round level IMO, but if he wants to establish himself firmly into the first round he needs to return back to college a la Brandon Roy.
As for Farmar, he's more into the first round than Afflalo is, but he could still afford another year of college. Actually this year's crop of PGs is fairly weak and he might have an opportunity to crack the #25-30 range, but he can afford to show even better playmaking and consistency in his jumpshot, even though both have improved slightly. Again, questions concerning his defense and athleticism, but his talent is undeniable; like Afflalo, he can take his game into another level in UCLA next year and put himself firmly into the mid-1st round or even late lottery.
