If M. Lynch isn't playing, it wouldn't surprise me at all to see the Lions get their first win in this MNF game (I can't believe I'm saying this- even in Seattle).
Stranger things have happened in MNF games. Without Lynch, I can envision the Seattle offense sputtering and Detroit has firepower when they play cohesively. It helps to have Golden Tate on the team too. He should have been able to share tidbits about Seattle tendencies for the Lions coaching staff to try to exploit. At the very least- the points do seem to bode in Detroit's favor in this desperation game (imo).
