Napier led Connecticut to the national title last season, prompting James to take to Twitter to praise Napier for the way he played and his NBA potential.
Napier was drafted in the first round of last month's draft by the Charlotte Hornets and then traded to Miami for two second-round picks. He joined Twitter the next day.
After James decided he was going to return to Cleveland after four seasons in Miami, Napier's Twitter account showed that he no longer followed James and all tweets sent to James were deleted.
Napier says he doesn't know how that happened.
"The whole thing about that is I don't know how to work Twitter yet and I'm not on my Twitter, so I don't know where that came from," Napier said, via ESPN.com. "I don't pay attention to it. It gets brought to me by family members, but I don't pay any attention to it. I just think it's how it is. Media wants something to bite on."
No way u take another PG in the lottery before Napier. — LeBron James (@KingJames) April 8, 2014
