I assumed most people consider CJ Spiller explosive, which is why I used that example. Doesn't mean he's good. I hated Spiller as a pro prospect because he had no contact balance or wiggle in tight spaces. But he's an explosive player. That's his meal ticket.
Miller was a better back but similar. He'd carry for 1 yard, -3 yards, 2 yards before exploding for a long TD. He ran for 1,272 yards in 2011 (exceeded by only McGahee, Duke and Edge) and did it primarily on the strength of big plays. His explosiveness defined him.
There are better backs in Canes history and plenty of viable candidates for most explosive. I like Miller because of his ability to turn those explosive plays into 6, even if he's 95 yards away from the endzone.
