There's a difference between having the option to make the deep throw and having the ability to do it. Andrew Luck throws the deep ball accurately, and with little effort. He's a powerful player through the legs, and drives his throws with his lower half in the same way a pitcher like Detroit's Justin Verlander creates "easy heat" by generating velocity without using a violent motion. Luck, however, simply hasn't had the option to throw the deep ball very often.
Stanford lost talented (and clearly underrated) wide receiver Doug Baldwin to graduation, and WR Chris Owusu has been limited this year by injuries. This offense is almost entirely built around Luck's ability to utilize tight ends and running backs to open things up on the outside, so people wondering if Luck can throw the deep ball need not worry; he just needs targets that make it worth throwing. -- Mel Kiper
