20 Two for One
Gain 150 Rec YDS each with a Bronze and a Gold WR
When You're working on the passing yards achievement you can get this one too. Just flip the 'Flea Flicker' play so you're bronze WR is the 'X' receiver. I used Jerry Rice and Alvin Harper
15 Over the top
Gain 200 Rec YDS with a Bronze WR
Since you've already got 150 yards with the Bronze WR in the previous achievement, throw another 50 yards and get another achievement
10 Pound it out
Gain 250 Rushing Yards with a Bronze Running Back in a single game
Just keep it on the ground. I used Christian Okoye and got the necessary yard in one 10 minute quarter. If you are worried you might lose yards, take him out after you get the necessary yards, as yardage achievements won't unlock until after the game.
20 You want me to do what?
Gain 200 Rushing+100 Receiving Yards with a Gold Running Back in a single game
Pretty self explanatory. Barry Sanders is always a good choice. Try not to do too many achievements in one game. It's terrible to finish with almost enough for a bunch of achievements. Try and focus on 1 or 2 at a time. This is one that takes some focus on one player, so I suggest turning fatigue to '100' so he doesn't get tired.
15 Ground Game
Score 4 Rushing Touchdowns with a Silver Running Back in a Single Game
Any Silver HB will do. If you're not good at the running game, pass until you get to the 1 yard line and have your Silver HB dive in for the Touchdown!

Break the single season record for INTs
The best player to use is the Night Train. He's a Gold CB. The easiest way is to simulate each game of the season, but check and see if he got at least one interception in the game. If he did move on, if not reload your season and redo the game. You need 16 for the achievement. Make sure you play the last game to get the achievement.
30 Spread the wealth
Finish the Season with 5084+ Passing Yards with a single player
Simulate all but the last game of the season. I used Joe Montana and Jerry Rice. Make sure you are at or around 5084 yards and play the last game of the season. This one isn't too tough.
35 Take it to the house
