I think KF just reinforced how much the depth chart after the starter matters...it's a toss up. Goodson got 9 carries and IKM got none. If you ask me...Goodson is going to see more time than IKM. It's not a situation where IKM isn't a good back...he just got beat out by Sargent for that style of runner...shifty, good in small windows, with some power. Goodson brings a style that the other three don't have...speed and burst, with good vision. Goodson can put pressure on a defense like the other three can't. If he got a few of the carries where Sargent was past the second level or Toren Young's cut back in space, where he didn't get much...Goodson has a chance to house a few of those is my guess.
I think you have to get Goodson carries to see what you have...he passed the first test...he held onto the ball, caught the ball, and finished every one of his runs going forward. Time to give him more carries.
