Cutler has been part of the problem, no doubt. But when he has protection, a solid system and a talented surrounding cast, he can play at a Pro Bowl level. He proved that in 2008.
Last year, they give him a shaky offensive line and a receiving corps still in the first trimester of its NFL development. Then, they bring in a new coordinator, making him learn his second system in two years, only to have the offensive line collapse.
At least Cutler has proved he can perform at a high level when given time, a competent running game and consistent playmakers at the receiver positions. What we don't know is whether the Bears are capable of giving a quarterback the tools he needs to be as successful as they need him to be.
