Nascar running 24 lame ducks against 12 that could still win the title is a huge part of the problem. To think that 24 drivers who are usually wired to be high-strung would ever accept being a placeholder or eunuch and just there to stay out of the way.
Hamlin aggravated, thinking Gibbs raced him too hard, and he could have taken Bell out while delivering the message.
I would fault Gibbs for running Bell three wide and especially for doing it while battling for something like 10th place, but Hamlin isn't justified imo.
Who would want a driver who isn't doing all he can to get to the front? What kind of message would that send to his team that is presumably giving a 100 percent effort.
