Pros: Porter is one of the more unique players in the draft, as he is the rare non-big-man prospect who influences the game primarily without the ball. Porter's lanky arms make him a great defender both on and off the ball, which is the area he projects to help most despite a lack of lateral speed.
Offensively, Porter is a smart cutter who can really open things up with his activity. Like most Georgetown products, Porter is a really good passer who shows an excellent basketball IQ offensively for a young player.
While Porter doesn't project to be a big-time scorer in the NBA by any stretch of the imagination, he's a definite glue guy-type of small forward, similar to a Tayshaun Prince or Matt Barnes. If his shooting keeps improving, he can be an excellent complementary piece for a team that has a few stars in place.
Cons: It's always scary to take a player who is good at many things but elite at none. Porter isn't a player who can beat his man off the dribble, and his light frame and so-so athleticism may hurt him on both ends at the next level.
If he's not in an offense that utilizes his intelligence, he could struggle. If he's asked to do much with the ball offensively, despite an impressive year as the focal point at Georgetown, he could struggle.
Although he's a pretty safe bet as a role player who impacts the game in a variety of ways, Porter doesn't project to be the star a team might want with a top-five selection.
