I think the argument can be made that Peppers isn't a good get because he doesn't fit the 3-4 scheme. Now I think he's the type of player that can and will adapt to anything because of his talent, but you can argue he doesn't fit. I get that, but I don't agree at all with the arguement that signing him would put in jeopardy the long term situations of Greg Jennings, Nick Collins, and Aaron Kampman. The numbers won't add up.
As far as trading the 9th pick for Peppers. I think that's what it would take. I don't think it will happen.
The experience in the 3-4 arguement though has been applied and as another poster said nobody on the entire team has it, but you do have to factor in that GB isn't giving up anything to get our own players.
However, do you take a player such as Brian Orakpo whom has never played in the 3-4 defense either over Julius Peppers? 9th pick isn't cheap. It will cost money to get him signed. Probably not as much as it would cost to get Peppers, but still a hefty amount.
Orakpo has zero NFL experience and could be a bust. I don't think he will, but he could be.
Peppers you can get possibly 5 more productive seasons out of him. Sure he could flop too, but he's proven he can play in the NFL.
5 seasons with Aaron Rodgers and this offense I think could put this team over the top similar to what Reggie White did for Green Bay in the mid 90's.
Yeah one player doesn't win you a Super bowl, but GB isn't winning the Super Bowl in 96 without Reggie White either. Perhaps Aaron Rodgers and Julius Peppers could be the equivalent to Brett Favre and Reggie White.
Regardless we'll probably never know, but it would be the bold move that I think this regime needs to attempt.
