Getting Great Players
While playing in dynasty mode, after the first off-season, pick up free agents that have an overall rating of 65 or over. Next, trade the players that you've just picked up for a great player and two horrible players (by horrible I mean having an overall rating of 30 to 40). They should accept your trade.
