Rodney Smith's father made him watch game film when he was "about 6."
"It was crazy," Smith said. "You're 6 or 7 years old and getting chewed out like you're in college."
Now he's in college and not getting chewed out at all. In his first game at Minnesota, the redshirt freshman running back carried 16 times for 88 yards and a touchdown, and caught one pass for 3 yards.
He earned a 100 percent grade from Gophers coach Jerry Kill.
Last time Kill gave a perfect score?
"I can't remember," he said. "Usually somebody goes the wrong way or doesn't pick up a blitz. To give you an example, we've got a lot of guys who graded out at 60, 70, 75 percent. That's pretty good for a guy up front.
"I don't think we've ever had one who played 46 plays and didn't make a mental error. That's hard to do in football. Certainly when you're a freshman."
The Gophers have produced three NFL-worthy running backs in the past nine years: Marion Barber, Laurence Maroney and David Cobb. Smith is this year's model. In the parlance, he's got wiggle and burst, juice and riboflavin. (This is a test: One of those is not a football term.)
