Shabazz Napier, PG
Napier will likely fall in behind Mario Chalmers and Norris Cole on the point guard depth chart, which puts a ceiling on the rookie's potential in 2014-15.
Still, as long as he can bounce back from his poor summer league showings, Napier will find his way on the court for decent minutes.
While out there, he should knock down outside shots, impress with his handles and develop as a distributor.
Projections (per game): 5.0 points (41.5 FG%, 37 3P%), 2.5 assists, 2.0 rebounds and 1.0 turnover
James Ennis, SF
Ennis dazzled throughout summer league play. He averaged 15.5 points (51.7 percent shooting from the field and 48.1 percent shooting from three), 5.0 rebounds and 1.5 assists in six games.
With his length and athleticism, the 2013 second-round draft pick certainly has the potential to carve out a great NBA career.
But his breakout likely won't come in his first year, considering the Heat generally don't like to rely on young players.
Still, Ennis should set the stage for a successful future with an efficient rookie campaign.
Projections (per game): 5.0 points (47 FG%, 36 3P%), 2.5 rebounds and 1.0 assist
Shawne Williams, SF/PF
The key for Williams this season is how well he can shoot the ball.
The 6'9" forward could fill in as a serviceable stretch 4 for Miami, but he'd have to be much better from three-point range than he was this past season with the Los Angeles Lakers (32.6 3PT%).
He shot 40.1 percent from outside in 2010-11 with New York, so it's certainly possible.
Still, Miami shouldn't enter the season expecting a big year from the 28-year-old.
Projections (per game): 4.0 points (39 FG%, 34 3P%), 3.5 rebounds and 0.5 assists
Justin Hamilton, C
Hamilton should make the roster due to his size (7'0"), age (24) and familiarity with the Heat (was on the team last year); however, it's unlikely he'll be much more than a benchwarmer.
Hamilton averaged 13.6 points and 6.8 rebounds per game in five summer league games in Orlando, but he also shot 28.6 percent from outside, which doesn't suggest he's truly ready to make an impact on this team.
Projections (per game): 2.0 points (46 FG%, 33 3P%), 1.0 rebound
Tyler Johnson, SG
Assuming he makes the team, which is far from a lock, Johnson is another guy who will see barely any playing time in 2014-15.
Johnson's young (22) and doesn't have the pedigree that others fighting for wing minutes have.
Still, he impressed during summer league play and makes sense for Miami as a young developmental project. Johnson averaged 12.2 points (54.8 percent shooting from the field and 46.7 percent shooting from three) 3.1 rebounds and 1.5 assists in 11 games in Orlando and Las Vegas.
Projections (per game): 2.0 points (45 FG%, 38 3P%), .5 rebounds
