Jarryd Hayne had a steep learning curve in year one. He still has a learning curve, but it will be significantly different in year two.
The past year has been a huge football education for San Francisco 49ers running back Jarryd Hayne. Having never played organized football, he had a steep learning curve. It was arguably a smaller curve than Lawrence Okoye, but still a fairly significant curve.
We saw some significant physical attributes from Hayne in the preseason. He did not get a ton of opportunities in the regular season, but the practice squad provided an opportunity to learn both about being a running back, and about the NFL on a broader level.
