Is it? A lot of fans see lottery and think "Payday" when in reality, there's a legit difference between being a high lottery and low lottery pick. If you have the measurables and talent to get noticed as a potential lottery pick, it makes sense to go through the camp process, find out what you need to improve, and go whole hog on improving that. Unless you are a surefire high end lottery pick, if you have multiple years of eligibility, with a staff that is strong with development, it makes sense to come back, unless the staff has told you that it's best for you to move on, for reasons not entiely basketball related.
Get the development minutes at the collegiate level, and then jump in the next year. Keep in mind, there are dozens of mock drafts and a lot of them are pure trash. I hope George isn't listening to anyone outside of L and the staff, because it's likely they are the only source giving him legit info.
