Against the Chargers, the Australian displayed more than just run prowess, catching a pair of passes for 17 yards and adding more fire on special teams with a 28-yard punt return. His play of the night, though, was this display of power at the end of a 12-yard grab in the third quarter. Chargers cover man Lowell Rose won't forget it:
"Our coaches are always (talking) about lowering our shoulders, you know, getting ready for contact," Hayne said, per The Sacramento Bee. "So it was just a situation that, all that training, all the hours on the field, (it was nice) to finally see it come together."
Coach Jim Tomsula has tempered his praise of Hayne throughout the preseason, but acknowledged Thursday: "Jarryd is a tough guy."
Hayne's playmaking ability, return-game gifts and overall usefulness to the team make him a lock for the roster in the eyes of fans and many analysts. Do the Niners agree?
We'll find that out by Saturday night as rosters are trimmed to 53 men, but it's hard to imagine San Francisco -- a team that's lost so much this preseason -- passing on such a fascinating player.
