Jay Cutler
Sometimes a player can have all of the physical tools but don’t put it together on the field. Many people thought that Tony Romo was the most overrated quarterback of the past decade but Cutler was even worse. The Bears stuck with him for eight seasons while he never proved he was the answer.

He infamously threw 26 interceptions in 2009 and 18 in 2008 as he regularly went into double-figures. His longevity meant that he holds many Chicago QB records but this doesn’t mean much. Remember, Chicago is where quarterbacks go to die and Cutler’s career sums that up (via Bleacher Report).
