The biggest storyline of tonight’s preseason match up between the Boston Celtics  and Philadelphia 76ers  is the addition of Elton Brand. But while Brand makes the Sixers an instant threat to the Cs in the Atlantic Division, the veteran isn’t the only player the Celtics will have to keep an eye on. The 76ers have a duo of young talent with promising potential who impressed during summer league play:
- Thaddeus Young: 12th overall pick in 2007 out of Georgia Tech … only 20, has enormous upside … gives the 76ers versatility with his ability to multiple positions … at 6’8″ could cause match up problems for smaller defenders … as a rookie showed maturity in 2008 playoffs (10.2, ppg, 4.5 rpg) against the experienced Detroit Pistons  … shined at 2008 Las Vegas Summer League (18.8 ppg) and got the vote of confidence from head coach Mo Cheeks.
- Marreese Speights: 16th overall pick in 2008 out of Florida … at 6’10” 245 lbs. is a beast on the boards ‘¦ ranked second in rebounding at Vegas Summer League (18.2 ppg, 10.2 ppg) ‘¦ gives the 76ers more defensive depth on the glass, which is critical to their fast break running game … think Al Jefferson  with more speed … could be dangerous once he becomes consistent at the line … Cheeks was happy with all-around summer performance and sees Speights learning from Brand this season.
