Yeah, I've covered this. And honestly, you can believe whatever story you want and still be partially correct.
JGR is about 75-80% responsible for no more FRR. Not 100%. But certainly (and intentionally) made the hill to climb
extremely difficult. That whole ordeal rubbed many people the wrong way, especially TRD, who, despite what many believe, DO NOT call the shots as it relates to any of the Toyota teams, or decide what they should do. They have a strong influence...like many big sponsors have a strong influence...but they do not make the decisions.
So, when you combine the JGR pricing with some sponsorship turnover, it just didn't make sense for Barney to continue. But he could have. There was still some potential, and he certainly had the cash to backstop the money hunt. He just chose not to. Never even really tried, tbh. I think that whole deal, mixed with his health (don't forget, they won the championship while he was at home recovering from a heart attack), as well as some family pressure was enough to make him step away. Call it a "forced, but probably for the better" retirement.
In summary: would FRR still be racing if JGR hadn't done what they did? Yes. Could FRR still have raced despite JGR? Yes.
Everyone here wins!!!
(And since it keeps coming up...I
have spoken to Barney privately. Many times. Even recently. He's a really good dude
)
