Franchise legend Ronnie Lott told reporters this week that he bumped into a couple from Australia and the National Rugby League convert was all they wanted to hear about.
Perhaps those fans are onto something.
Though the now 28-year-old was cut last year, the team re-signed him to the practice squad and eventually bumped him back onto the 53-man roster. Hayne had 17 carries for 52 yards and six catches for 27. He also returned eight punts for a total of 76 yards.
It was enough to catch the eye of Paraag Marathe, a 49ers executive who is in charge of the team's analytics department. Marathe also weighed in on Hayne.
"I think you'll see a jump from him," Marathe said, adding: "You look at elite athletes and those guys who have that willpower and desire to succeed and there's something special in them."
