re: What's the biggest problem with this team?

To me experience and talent throughout the roster. Two examples:

1) The majority of the offensive line has reached maximum capacity to be coached up. Three of them are SEC caliber and two of them are freshmen, and only one started.

2) Like it or not, the starting QB has the physical tools but he looks like some dolt trying to catch dust particles with tweezers in a dusty cabin when on the field.
