Lance is the best player in NYC. He's definitely top 10-20 in the country. Mentally he can be a bit too unstable at times during the games. But he's a real physical spicemen. He really reminds me of Lebron James, in that he powers his way to the basket and is tremendous at finishing. He has to work on his jump shot to be a successful pro though. I don't think he's a lock to be a NBA player...
Kevin Parrom and Durand Scott are both very good. I think both and Omari are on the level, which is probably around 45-70. I don't think they are program changer, in that if either one came here we would be immediate contenders for the NCAA tourney (unlike Lance), but I do think they will be very good players once they a junior/senior. For Scott, I can even see him being a surprise as a freshman, and defintely good as a sophomore. But I doubt they can be stars right away like Kemba Walker.
I've only seen Lamont Jones once, so I can be wrong. But I don't see him as a real high level/great get, like the others above. If I had to rank him i'd probably say somewhere in the range of 100-150. He will probably be a decent bench player, but I do'nt see him has a great impact player.
Trust me, I'm thrilled Omari is coming. It's Norm's best recruit. But he's not 25 material. I just don't see him being a great impact player right away like Lance.
