My Oklahoma Outlaws are actually using a color scheme i found on the net, when i searched Madden Teams.. found a decent color combo, (Red, Silver and Black), and used the logos the game offers as The bandits. looks pretty pimp, just play with the uniforms with those 3 colors, and you will find something you like. There are tons of other options on that page as well.

As for setting up the roster, what youve gotta do, is set your roster the way you want it in the Roster file, BEFORE you start a franchise. Usualy what I do is go through,a nd first off, trade anybody worth a damn off the tema im going to replace (Usually jacksonville or St. Louis)
typical 1 for 1 trades, i'll send MJD or S-Jack to Seattle usually, or Cleveland, and just take their worst RB they have in return.
Then i wil release guys off the roster, to get it to a 50 man roster, (which is all you can use in Fantasy draft team in C-A-T menue)
So now, ive got a team full of scrubs, and a few rookies (The rookeis actually drafted by the team, or my own picks if i do it differently) Then i will trade off whats left, to get the guys i "acquired" in the fantasy draft. Say i draft QB Sage Rosenfels, id trade the best QB left on my team (Bulger or garrard would be gone by this step) and do the same with every other player needed to get my roster exactally how i want it to be when i start the franchise.
Next step is to WRITE DOWN the players, by position, and then create your team.
Draft all the players written down to your team via the Create a Team menu, and save, and load them up and start a franchise.
This should result in zero duplicate players, and you should be ready to get off the ground for the 2009 season.
