Green is the starter if healthy. But Green isn't healthy at this point and isn't planning to be in the immediate future. The track record for players returning from the injury he had is very poor. (To be fair, not many players have had his type of injury, either). Based on that, Green is a risky pick for this seasons.
The Packers rushing totals for RB last year were nothing to write home about (367-1247-11). They did utilize the RB in the passing game a lot, though (116-881-2). It's unlikely that Green is going to get the workload he did in 2003 (405 touches) coming off of a serious injury. At his point, how Ahman does this year is really a big question mark.
Just two things from a Green Bay homer as a FYI.1) Mike McCarthy is the new HC and will be calling the Offensive plays and has been preaching a power running game since he got into the job. I don't think that this is just lip service. If I had a guess I'd say that there will be a bigger commitment to the run in play-calling then Green Bay has seen for a long while.
2) The new offensive coordinator is Jeff Jagodzinski. He has been the O-line coach in Atlanta the past couple seasons. He is implementing the Atlanta/Denver zone blocking scheme that he learned from Alex Gibbs in Atlanta. The O-linemen he has are more prototype zoneblocking guys (which explains why they like their second round pick, Daryn Colledge so much). Both Ahman Green and Samkon Gado ran the zoneblocking scheme extensively in their college careers.
3) With both Davenport and Green injured, Gado is getting pretty much everything in the minicamps and OTA's (and there doesn't seem to be a big push to find more guys for the slot). Gado has been in Green Bay the entire offseason and Mike McCarthy is very high on guys that have spent the time working out in their offseason program. He's going to get a ton of reps. A ton of work. By the end of training camp, there's no doubt in my mind that Samkon Gado is going to be the RB who is most familiar with the system. Keep a good eye on him.
Green with a Gado handcuff might be pretty darn good value.
