Both are/were great drivers. My opinion it is an unfair comparison and no-way "twice as good". Kind of hard to compare when they are 10 years difference in age, different racing classes along the way, etc. Bobby has been in a full blown late model for what- 4 or 5 years now? I don't know if Justin even raced a full blown late model for 4 years straight.Justin had moved to ARCA at 16-17 years old. Bobby was in a kid's mod(full body car) at like 8 or 9 years old, Justin was in a mini-sprint. So if the comparison was Bobby in a full blown late model and Justin in a full blown late model, then maybe yes. If the question is "driver" on their way to the big leagues, not even close to twice as good! JMO
