Diamond Dallas Page says Dusty Rhodes would have been overjoyed to watch his son, Cody, in the main event at WrestleMania 39 ... telling TMZ Sports "he would be walking on clouds."
Page -- who mentored his late best friend's son since he was a kid -- told us Cody's heavyweight championship match against Roman Reigns on Sunday, April 2 is the culmination of a journey, and a moment the Rhodes family can savor forever.
DDP explained the fact that Cody left WWE in May 2016 when he felt the company didn't believe in him, and then came back to have a monumental moment like the main event at WM 39 is proof of what can happen when people believe in themselves.
