There is also plenty of excitement within the Michigan fan base, and program, about freshman early enrollee J.J. McCarthy, a former four-star, top-50 recruit nationally. "J.J. was terrific as a mid-year freshman, and got himself all the way up to No. 2 [on the depth chart]," Harbaugh revealed. And then there is freshman Dan Villari, who did not appear in a game last season. At 6-4, 227 pounds, Villari is a dual-threat quarterback with a lot of strength. Harbaugh said the Wolverines are experimenting with some of the things they can do with Villari, moving him around and finding a way to get him on the field.
