CHARLOTTE, N.C. — It's been almost two decades since Morgan Shepherd last ran a full Sprint Cup season, and his last national series victory was in 1993. He can still probably wheel a race car better than you and most of your friends. That doesn't mean the 72-year-old should be racing against the very best drivers in NASCAR. Shepherd drew scrutiny Sunday at New Hampshire Motor Speedway when he caused Joey Logano to crash.
