Giants beat writer Jordan Raanan of NJ.com wonders about the role of RB Andre Williams:
Rashad Jennings ran primarily with the first-team offense. Free-agent acquisition Shane Vereen was mixed in constantly, especially on passing downs. Where does that leave Williams, the second-year back out of Boston College, after a strong rookie season? Williams might have trouble finding a role if the other two stay healthy. Jennings may even be a better, more effective short-yardage and/or goal-line back.
Williams averaged 3.3 YPC as a rookie (Jennings averaged 3.8 YPC), so the team probably isn't making it a priority to get the second-year back on the field. It appears that Williams will serve as Jennings' backup, so as long as Jennings stays healthy, he should see the bulk of the carries on 1st and 2nd down.
