Ty will have some nice games...but I don't think the model against the Bears will work for the rest of the year.
Teams need an RB to pound the ball.
I think Knile gets a shot...but not sure he ever gets more than 15 carries or so. Even Lacy wasn't getting a ton of carries.
Ty will still get 5-10 carries and a bunch of looks out of the backfield as that versatility has made the offense work a bit better.
I would say Knile may be an ok stash as a just in case...or a bye week/injury filler. But when Starks returns, that may get muddied up even more.
I don't see a consistent FF performer as an RB in GB.
