Agreed. In two of his three successful years in Denver, he played better than in his previous year with Indy. His TD % was higher (more TD's), had around same yards, and lower INT %. And the other year he wasn't good, he was GREAT!!!
But...it was 3 years of Manning the Colts could have had...and maybe they would have won another championship with him one of those years. So the question will be, was Luck worth losing out on another SB ring?
In fairness to the Colts, no one even knew how well Manning COULD play coming off the injuries and the money he wanted was very high! Made sense to get rid of him and draft the next stud qb!
