When I use the NE Patriots, I make Woodhead my starter and substitute "The Law Firm" [Benjarvis Green-Ellis] in for my "grind it out" plays.
When I use the 49ers, I start Gore, but sub Westbrook in on "passing" plays/formations. ghore is a solid receiving back, but Westbrook made his career this way. Also, like real life, i tend to take gore out when I'm inside the red zone. At least until last year, gore had a problem of fumbling inside the 20. As a result, Michael Robinson carried the load along with rookie Glenn Coffe [
] now I use Anthony Dixon for Red Zone or Inside the 5 situations.
In the end it's up to you, the user, to do this yourself.
