Well, today's news out of Green Bay was not exactly comforting. With Eddie Lacy already ailing, we found out James Starks did not practice due to a knee injury. If both Starks and Lacy are unable to go, Sunday's contest with the Cowboys could prove to be quite a conundrum. In lieu of signing a free agent, Green Bay would be well-served to elevate practice squad back Don Jackson ... but don't be surprised if they don't. At least one report suggests Ty Montgomery took a bulk of the carries at Wednesday's practice and we all know Randall Cobb has been used in that same capacity in the past. While I'm all for innovation and diversifying your offense, it seems like a stretch to ask a wide receiver to be your full-time back. Having said all that, it's also no secret Green Bay's offense seems to be most effective these days when the ground attack is firing on all cylinders -- meaning Lacy is playing well. It's not to say the Packers can't win without him. They obviously still have Aaron Rodgers who, despite recent criticism, is still a very good quarterback. It's just that the challenge becomes that much harder against a team in the Cowboys that already appears to be doing everything right. Only time will tell with injuries, but it's safe to say the next 48 hours will be very important to Lacy, Starks and the Packers' offense.
