Crowell is running behind a much improved O-line and he ran well last season (almost 1k yds on less than 200 carries) behind a poor O-line. the Steelers D isn’t anything close to the Steelers D of old. And Crowell also caught a decent amount of passes last year so if Kizer is going to start, I can see a good amount of check downs going to Crowell.
Cook is the lead back playing against a bad defense. That said, NO always puts up a lot of points so MIN could end up just having to chuck the ball and if he’s coming off the field on 3rd down that greatly limits his potential touches.
Ty is playing against a good defense that just got a lot better up front with their trade for Richardson.
I’d go with Crowell, Cook, Ty in that order.
