What are you basing that on? Their 247composite ratings? Videos? Having seen them play?Here's the Kool-Aid. I'm all over it, but the thought of Goode and Melendez being key contributors on a good team, as freshmen, seems remote. If Kofi comes back....he in conjunction with Curbelo, different story.
They probably have the raw talent and offensive skills to contribute right away. It depends on how well they can play defense. They actually bring some things to the table the current team lacked.
