Alvin...
Calm down...
It was just a minor scuffle - no punches that I saw.
A few words directed towards a young self righteous punk. No comments about NASCAR - just some comments about another driver.
As far as comments like "I'm going to get him..." Logano said the same things last week about Hamlin. Logano didn't get suspended or fined, so NASCAR is being entirely consistent.
"Boys have at it" is ongoing. As long as there isn't any blatant retaliation (which there wasn't - it was just Logano's lack of skill that caused him to take Denny out) - it's just business as usual.
Until they start dealing more strictly with the Bash Brothers - there really isn't too much they can or should do to the other drivers in NASCAR - most of whom are actually good for the sport.
