It is possible that Andrew Luck is secretly available for trade in the right deal. He missed a year and a half of football. That's a lot. Colts stink, they have a lot of needs, and their O-line is non existent. And he has a huge contract. Durability is a major problem, too. Even the owner hinted (in a nice way) that Luck is soft.
If I was Luck, I demand a trade to my agent.
