One week can't determine whether or not the Indianapolis Colts made the right decision by selecting Andrew Luck over Robert Griffin III, but Luck's performance Sunday against the Green Bay Packers proves his value to fantasy football owners.

Luck dropped 362 yards passing on the day, two touchdowns and only one interception. He attempted 55 passes in the game.

Luck won't stop throwing the ball 40 to 50 times per game. His attempts will stay around that range throughout the duration of the season.

Offensive coordinator Bruce Arians, who held the same position with the Pittsburgh Steelers, loves his quarterback too much; the now-interim head coach will ride and die with his quarterback until the bitter end.

Luck has already attempted 177 passes this year in four games. That averages out to be 44.2 per game. For a rookie quarterback, that is absurd.

Sure, he'll go through his rookie lapses, but he has proven to be mentally tough despite having to live up to lofty expectations set by former quarterback Peyton Manning.

Luck is averaging 302 yards through the air per game. He has also racked up 95 rushing yards in the past three games.

So while he may not be as extremely athletic as Griffin, who racks up fantasy points with his legs, he's not too far behind in overall athleticism.

When to use Luck on your team

Depending on your league, Luck would be a great option when your quarterback has a bye or is out for a week or two.

It will be risky using him for the duration of the season, simply because of rookie stretches, but he's certainly capable of holding down the fort for a couple weeks.

That's more than you can say about most rookie quarterbacks.
