Why Tennessee might be the best college football team in the nation

Nico Iamaleava and the No. 5 Tennessee Volunteers are rolling.

In-between a pair of overwhelming wins over Chattanooga and Kent State — by a combined score of 140-3 — Tennessee pummeled then-No. 21 North Carolina State, 51-10.

In what's his first full season as the starting quarterback, Iamaleava has totaled 892 passing yards, seven passing touchdowns, two interceptions and a 176.2 passer rating, while completing 69.3% of his passes. He has also rushed for 117 yards and one touchdown. Meanwhile, running backs Dylan Sampson and DeSean Bishop have combined for 736 yards and 13
