Portland Trail Blazers
Noah Vonleh: If there's a consistent market inefficiency in a rapidly evolving league, it's young players who will fail to produce right away in their rookie seasons. Everyone knew Vonleh would be a multi-year project, and yet the Hornets bailed on him to acquire
Nicolas Batum on an expiring contract anyway. The game may be moving a little too quickly for Vonleh now, but that should change with time.
Keith Bogans: Yes, it's him. You may not recognize Bogans without the words "non-guaranteed contract" immediately preceding his name, but it's him. The journeyman will be the oldest player in summer league at the age of 35, and it's more than a little surprising that the 11-year veteran is even here. Of course,
Rasual Butler turned a solid summer league into a legitimate role with the Washington Wizards last season, so you can never say never.
Meyers Leonard: The man known as Legend really came into his own late in his third season, entering the elite "180 club" of shooters after posting shooting percentages of 51/42/93. Leonard probably won't be able to maintain anything close to that level of efficiency in an expanded role with more minutes, but he's a young player worth watching all the same.
