Reggie Bush says Saquon Barkley's gonna waste no time dominating the NFL ... telling TMZ Sports the ex-Penn State star is more pro ready than he was coming out of USC.
We saw Bush -- regarded by many as the top player in the 2006 NFL Draft -- and asked who was more NFL ready heading into the draft ... him or Barkley.
"I think Saquon is more ready, prepared, going in. Just because his running style to me translates right now to the NFL," Bush -- the #2 overall pick in '06 -- tells us ... "For me, my first year in the league there was a learning curve of how to run between the tackles at the NFL level."
"There was an adjustment period for about 2 years, I would say. Before I really got comfortable running between the tackles" ... RG says.
But Saquon ... Reggie says he'll be ready to go from the jump.
Bush also tells us who he'd pick #1 ... and which QB is the best in the class.
