I guess that it would have been different if they were in the Car of Yesterday, the COT is simply killing Montoya and his teams chances. From a top 5 in Atlanta, he went to be a regular in low 20's, and even if he will improve in Sunday, he will not win this one.
If every race is going to be on COT next year, and Ganassi don't improve, he should eval if being a midfielder in NASCAR is better than being a midfielder in F1.
