In measuring Andrew Luck's toughness, don't just look at the hits he takes, or the hits he's dished out, or even his willingness to get out and block on a reverse. His toughness starts before the hits ever happen. With Luck, it's all about progressions. His toughness is found there, because even in the face of a rush, he keeps his eyes down the field, gets through his reads and steps into contact to make the right throw.
So many times we judge a quarterback's toughness on his ability to take a hit. But what kind of throw he is making before that hit arrives and what kind of decision-making process he's going through as pressure builds are pivotal. I'd rate Luck similarly to a guy like Peyton Manning in terms of toughness, and we know Manning is as durable as he is gifted. But it's not just because he has the size to take a hit. It's because he is willing to take a hit to make the throw. -- Mel Kiper
