The game Foster played in week 2 was against KC, and that was B4 they decided they would just stack the box..
At that point in time KC was a HS run defense ( remember Q shredding them inb game 1... he's done jack since), that got pounded. -32/174 ( he had a monster run of 71 yds, and had 103 yds on 31 carries besides)
Game4 was against a good run D in Atlanta, and he was nowhere near as effective. 19/51
I don't think he is bad or a real stud, I personally think he is a good back who has some explosiveness, especially against weak run defenses.
Davis will get his shot, maybe not really this week though.
Don't blame us if your players stink the place up....You got our OPINION, your not paying any money for advice!!
If your new guy gets injured.. it happens, and not part of the equation beforehand.
Good Luck, and Thanks for being reasonable.
