Also consider that Rams may need Williams more than the Bills need Cook. Williams is a 3 down back and the Rams #2 RB is Ronnie Williams who rushed for a whopping 99 yds. last year. Now I'm not saying Cook is easily replaceable, but Davis had 442 yds at almost 4yd a carry in a limited role and presumably would get better with more touches. Ty Johnson is also no slouch and is a great blocker and receiver.
I want Cook back as much as everyone else, but he has to be reasonable.
