Big Board: Alex Len moving up

Following the league's organized workouts -- including the Las Vegas workout earlier this month -- NBA team workouts are in full swing as draft boards around the league continue to shift.

So who's rising and who's falling? After talking to scouts and GMs from nearly all 30 teams, here's our latest ranking of the top 30 prospects for the 2013 draft. (Click here for the previous top 30 update.)

Also, be sure to check out our updated Top 100 and our Mock Draft 4.0.

1

Nerlens Noel

SCHOOL: Kentucky
AGE: 19
HT/WT: 7-0, 206
POS: C

10.5 PPG
9.5 RPG
4.4 BPG

Noel's hold on this spot has never been more tenuous. Yes, his doctor, James Andrews, is pleased with his rehab, but are teams willing to be patient with a player who might not be ready to play until early next year? Especially when he's one of the most developmentally raw players in the draft? After telling me all year the answer to those questions was "yes," it sounds like some of those teams at the top have changed their answer to "no." Even the Cavs' desire for Noel appears to be waning. The only thing saving Noel from dropping a few spots on our Board? Who is going to replace him?

2

Victor Oladipo

SCHOOL: Indiana
AGE: 21
HT/WT: 6-4, 213
POS: SG

13.6 PPG
6.3 RPG
2.1 APG

Oladipo had his first workout last week -- with the Suns. Oladipo's main competition at the workout was Shabazz Muhammad (Ben McLemore was also in Phoenix that day but declined to work out with Oladipo or Muhammad). By all accounts the Suns (like just about every other team) were impressed. Sources say that Oladipo has moved into the Cavs' conversation for the No. 1 pick and also is under heavy consideration from the Magic at No. 2. Sounds like it would be a surprise if he goes past the Suns at No. 5.

3

Otto Porter Jr.

SCHOOL: G'town
AGE: 20
HT/WT: 6-9, 198
POS: SF

16.2 PPG
7.5 RPG
2.7 APG

Porter has yet to work out for a team, but in the coming days he'll hit Cleveland, Orlando and Washington -- that's it. He's seriously in the mix for both the Cavs and Wizards and seems to be confident he isn't sliding past Washington. If he does slide, there's no way he gets past the Pelicans at No. 6.
