The fourth-year back started seven of nine games and led Seattle with 117 carries, 469 rushing yards and six rushing touchdowns; he was also a top-five target for Russell Wilson out of the backfield (20 rec, 96 yards). His carries, however, had diminished over the past two weeks.
Prosise has come on as a dual-threat force over the last three weeks. He paced Seattle's ground game against New England on Sunday night to the tune of 66 yards on 17 totes, while Michael earned but five carries. Prosise was also used effectively in the slot as a vertical receiving threat, hauling in one impressive wheel route for a gain of 38 yards en route to a 87-yard receiving night.
So Seattle will move on with Rawls, Prosise and recently-elevated Troymaine Pope, and without Michael, unless the latter sneaks by the waiver wire, which is unlikely. Though he may be hampered by a hamstring injury that landed him on the Week 10 injury report, we'd be surprised if a running back-poor playoff hopeful didn't take a chance on Michael -- ahem, Giants, Vikings, Ravens, etc.
