I own all 24 expansion teams. And all the teams are really different. Some are really good at something, or just average, or very poor or a combination of the aforementioned. To me, my Bengals roughly equate to the Virginia Beach Valiants. If you are really gungho, you could take the dice and mix them up and then formulate fairly decent representations of each real life team. But be forewarned, this game is NOT a simulation. You would have to house several things. For example, if you guess the right play, you will shut that play down. The heart and soul of this game is trying to out guess your opponent. In other words, an individual player's talent is not factored in, per se. If you can live with that, yes you could customize teams.
