Tim Hightower has been explosive, dynamic, productive, and many other wonderful things this pre-season. He's averaging 6+ yards-per-carry, and maybe, just maybe, the combination of a) an explosive one-cut runner like Hightower and b) Shanahan's perennially successful zone-blocking scheme will result in a dominant Redskins rushing attack.
But I'm nervous. Hightower has always been an explosive runner, this is nothing new. Last year, among the 55 RBs with 60 or more carries, Hightower was ranked 8th in Yards Per Carry. The problem is that Hightower has been fumble-prone. And as many statistical analyses have shown, no single statistic predicts wins and losses better than turnovers.
