Usually this time of year, ESPN and or Sports Illustrated publish comprehensive lists of all early entires, but I have yet to see one.
Has anyone else? Seems we have been lucky this year with minimal impact from the early departures (keeping fingers crossed till deadline).
Here's a list I pulled from cbssports.com. This year there have been a record 72 early entries in the draft. Also, players have until tomorrow (January 15th), to declare their intentions to return to school or leave early.
