LeBron James ... 4-time NBA champ AND Pro Football Hall of Famer?!
Drew Pearson says he can make that a reality for the King ... telling TMZ Sports if Bron switched to football and joined the Cowboys, he could turn the Lakers star into a HOF receiver!!
"If I had a chance to work with him at wide receiver or tight end, he'd become a Hall of Famer, that's for sure," Pearson said.
"He'd become a Hall of Famer because he's got that talent, and with my coaching, I can coach him up to become a Hall of Famer and get one of these rings.
