I would think that once time for voting comes, the field will be necked down to no more than 5 with realistic chances of winning. At this point a more close look at each candidate's body of work can/will take place. This works in Ingram's favor.
First, this closer look is where/when his YAC (Yards After Contact) numbers will be aired. Truely, this is where he most seperates himself from the rest of the players in college football.
Second, this is where the "What he means to his team" element comes into play. Considering that this Bama team started the season with question marks in the form of "unproven Offensive Line and Quarterback", he will be given much credit for all that he has done considering these issues, playing in the SEC, and carrying his team to National Championship contender status. Neither Tebow nor McCoy have added that to their resume.
Third, whereas Tebow will have the "All-Time SEC rushing TD record" to his resume, he will still be seen as a Senior who has slipped statistically. Ingram will be a Sophmore who bested every Running Back in Alabama history, while improving.
Fourth, should Bama beat Florida the head-to-head victory would be something that McCoy can not answer.
Much is in Mark's favor, but there is still a long way to go.
