This clearly shows how little you r are thinking about the situation and how you aren't reading what I am posting.
Everyone knew when he signed with the Chiefs that, barring a TJ cut, McClain was being signed to be a FB. That isn't the question, the questions are is he going to be a FB with 0 touches a game or 5-6, is he considered the #3 RB if one of the top two go down, or just a backup to TJ (with McCluster as Charles' relief) or will he remain the FB even with injuries in front of him. Will he get none, some or a significant # of goal line touches.
All of these possibilities have fantasy implications, your posts give no insight into them at all.
Whatever helps you sleep at night, bud. The HEAD COACH, and McClain himself have admitted that he isn't going to take carries from Charles/Jones, that he is there to be the FB, and that he is there to open holes for the two RUNNING BACKS.I don't need to use convoluted thinking, and faulty logic to try to create support for a weak hypothesis that because McClain signed there, he was promised/expects more carries, when ALL information from the team and player suggest the opposite.
If you wish to continue to continue to think McClain signed in KC because they (KC) met his demands for more carries (which was your original premise), based on whatever weak "logic" you come up with, good luck to you.
