In that regard, today's scrimmage is huge for the newcomers hoping to catch the coach's eye and be "in the mix" when the season begins.
As Fulmer conceded following Friday's practice: "It's a big day for us to test some of the young guys."
The scrimmage - closed to the public - will consist of roughly 100 plays.
Although many positions remain up for grabs, the Vols are especially uncertain in their receiver corps and their secondary. That's why today represents something of an audition for first-year wideouts such as Kenny O'Neal, Brent Vinson and Gerald Jones, along with rookie defensive backs Nevin McKenzie, DeAngelo Willingham and Eric Berry.
"We're going to go at it pretty good," Fulmer said. "It will be great for those young defensive backs and receivers to see how they handle it."
Tennssee came through its first week of practice relatively healthy. The only key player who will miss the scrimmage is linebacker Ellix Wilson, who has a minor knee injury.
