I hope neither rush the process by hiring an agent.
Briscoe isn't going to get drafted. Anybody telling him different is not doing him any favors. With that said, his stock or lack there of isn't going to change if he comes back. He could very well be an over seas guy. Nothing wrong with that, great money and lifestyle can be had overseas.
Bam is going to get drafted, but he can improve his stock. Right now he is a 16-26 pick, if he wants to take that to the bank, great, I don't blame him. However, if he thinks he has some room to grow and improve at this level and can help his stock, that's great as well. I think Bam has top 8 potential, but didn't quite show it this year because he had no help down low and Cal ran a guard oriented attack due to the lack of a front court.
