Besides some blocking action at FB against the Cardinals and possibly Redskins, here's what we have to go on for Mills so far:
4th quarter of the NE/ATL game:
He lined up as a blocking FB a few times on runs with Thomas/Rasby at TE. But all of his catches were out of the SLOT as a WR. Never did he line up as a lone RB. He isn't going to replace Faulk.
