Believe me I am no Johnson fan but here are the facts.
- Earnhardt wrecked many people for his wins.
- Petty had superior equipment for his until NASCAR regulated equipment.
Jimmie Johnson has won 5-STRAIGHT championships where the limitations and rules are as strict as they have ever been. Not to mention he rarely has used his bumper to win races in the stretch. It is easy to win when your engine is 50 HP more than the closest competitor or you wreck your only competitor.
You mean to say Hendrick and Knaus don't have an advantage over the rest of the field? They know something that the rest of the teams don't know. That's an advantage.
I also don't see the problem with using your front bumper to win. More exciting racing. It's fair game IMHO, just expect payback if you do it to someone.
