I drafted Jones last year, and had the same problem. I avoided him this time around. I also avoided all Bills running backs.
Mostert was just a random, "well Mike McDaniel likes running the ball why not" moment. And I thought Breece Hall would be catching passes from Rodgers...
I have Aaron Jones and he's missed practices all week, it will be known today but even if he's active, they're not giving him full workload. I have lost 3 weeks at least by trusting him that he'd be back to week 1 form before he got injured. That very high draft selection and roster spot seems wasted at this point, and It would be a wonder if he's back to that form this year. Maybe, he's injured all year and those hamstrings get better only after off-season.
Good luck, anyway most important w weeks are playoffs and that's when the players have to earn those big points for us to win.
