I completely agree with this. Also, in addition to this:
-no exploiting the CPU in any possible trades,
-try intentionally letting some good FA's walk in free agency if you had a good season the year before,
-consider changing offense play books before a game (to avoid repeating "money" plays/routes, and then during the game using "Ask Madden" and then using your own discretion to choose 1 of the 3 plays presented),
-and try to avoid excessive hot routing/no huddles.
