Trent Dilfer was one of Josh Rosen‘s toughest critics early in the former UCLA quarterback’s career, but now Dilfer is signing Rosen’s praises.

On the Rich Eisen Show on Wednesday, Dilfer compared Rosen to some of the elite quarterbacks of this generation. The former-NFL-quarterback-turned-ESPN-analyst said Peyton Manning, Tom Brady, Drew Brees and Aaron Rodgers are “not always the best people to be around,” but “they demand the best from the people around them because they want to be great.”

“I think Josh has that in him,” Dilfer said.

Dilfer, who coached a 17-year-old Rosen at the Elite 11 in 2014, was tough on the former St. John Bosco recruit. He said Rosen was entitled and uncoachable when he came to the camp. But when Rosen served as a counselor this past summer, Dilfer was swayed by the UCLA junior’s humility to return and work with the next generation of prospects.

“He’s intellectual. He’s got conviction. He’s not going to be wishy-washy on stuff,” Dilfer said, “and he’s going to demand that his coaches give him the best stuff because he wants to be the best.”
