Each week we release the Freshman Tracker, and each week there are new names and plenty of movement. This week is no different, with two newcomers.

For this week's edition, we’ve added a section on what the top 10 first-year players in the country need to improve to become even more well-rounded.

1. Jabari Parker, F, Duke Blue Devils

6-foot-8, 235 pounds

Parker rebounded from a subpar shooting effort against Arizona with a solid effort in Duke's big win over Michigan. He finished with 15 points (most of them in the post) and six boards in the victory.

Needs to improve: Parker is as skilled on the offensive end as any freshman in a long time, but he needs to improve on the defensive end of the floor. One coach also told me that he’s such a gifted scorer that he takes it for granted and isn’t always as sharp as he needs to be, such as being in position to catch the ball in the proper spot.
