Philadelphia Eagles coach Chip Kelly has said that new quarterback Sam Bradford can become one of the all-time greats.

Bradford didn't play for the St Louis Rams last season through injury, but Kelly isn't put off and believes that they couldn't have signed him if he was playing regularly.

He told NFL Media: "When you look at all the great quarterbacks, Peyton Manning has missed a year, Tom Brady has missed a year, Drew Brees has missed a year. Again, we felt like to get a player of Sam's calibre, it wouldn't have happened unless he was injured."

Eagles owner Jeffrey Laurie told reporters yesterday that Bradford was "the best young quarterback we'd seen, probably since Peyton Manning coming out of college".

Bradford joined the Eagles earlier this month, while Nick Foles was traded to the Rams.
