First, take your 1st round pick, and trade it to New England for their 1st, 2nd, and 3rd round pick.
Take your second round pick, and trade it to Jacksonville for their 2nd, 3rd, and 4th round picks. Sadly, you'll get a message telling you that this will exceed the rule of having only 10 picks per team. (there is no rule, Madden basically made it up. NFL teams can have as much picks as they like). Throw in your 7th round pick to please Madden.
Now take your 3rd round pick, and trade it to Seattle for their 3rd, 4th, and 5th. Throw in your 6th, and 5th picks in order to keep it under 10 picks.
Your picks should now look something very close to this.
Take your 4th round pick, and trade it to New England, and take Seattle's 5th round pick, which you now have, and also trade that to New England.
Your picks should now look similar to this.
First round, you are picking first.
Second round, you get first and second back to back picks.
Third round, you get First, second, and third picks all in a row.
4th round same as third, First, second, and third all in a row.
5th you get the first pick of the round.
