This just gave me an idea, instead of going young like you I'm gonna do a 2011 version of the Over-the-Hill Gang...
Being a Packers fan there's not a whole lot needed to do, but I have found it extremely hard to use Grant as my running back in 11 and 10 without messing with the games speed/ sliders, so I typically try and get a big play back or make plans to pick one in the draft after year 1 (I'm currently planning on picking up LaMichael James when he graduates in my Oregon Dynasty on NCAA 11).
Like Rodgers my favorite target is Finley, I've always enjoyed using the TE (started back in Madden 2001 with Bubba Franks and All-Madden TE #89), so that's an important part of my offense.
Defensively I like freaks, Clay Matthews, Charles Woodson, Polamalu, Ed Reed, Suh; guys who can beat you with speed or strength, and give you dual threats (hard hitting, ball hawk - Polamalu, Reed, Run coverage and pass coverage - Woodson, and can beat the line with speed and strength - Matthews, and Suh). You get a couple of guys like that on your D and the rest can be somewhat of a constantly changing cast, if you can put together a D like the packers, steelers, and the Ravens (more so in the past) you can allow for turnover at some positions (if you maintain freaks at key positions you can allow players to come and go, you can let AJ Hawk go at the end of his contract as long as you have a Clay Matthews still on your team). Like the Packers I like to have top players and let lesser known guys step into the roles (think BJ Raji).
