If you're running him without anything but the sugar strat card he's kinda meh.
On the other hand, if you're running him with the sugar strat card and legendary Sprinter strat card he's an elite RB that for around 420k would be worthwhile for a lot of teams.
His stats for me...
98 SPD
99 ACC
96 AGI
98 CAR
78 CTH (meh)
99 COD
98 TRK
99 BTK
He gets Bruiser for free and I'm running Joystick for 1 AP and Reach For It for 1 AP for a total of 3 abilities for 2 AP.
He's not in the same league of shedding tackles like Gus, Quadfather, Henry, or Flash but with X-factors being limited to 3 players he may be the best unpowered running back.
I really liked the Game Changers Jacobs when I tested him and thought he was the best RB without an X-factor. I still think he may be without the legendary Sprinter card. If you do have the Sprinter card I think Stevenson is worth a look. Without it he didn't have the same burst on short yardage situations.
Thank you for your time.
