The man will be 42 in May. He's not married, even though he has stated that he wants a family. I've seen no evidence of a girl friend on pit road this year. He has to relieve the stress in his life somehow, and he's chosen dirt racing.
As far as personnel changes. I know that Tony & Zippy has issues before he left Gibbs. That was 5 years ago. Zippy had to deal with Joey - the non-starter that was billed differently. 5 years is a long time in racing. I'm not throwing Steve Addington under the bus, but after last year's early 3 wins, then nothing, you have to wonder. Tony hasn't forgotten how to drive, maybe he's just not getting the equipment that he needs. All I'm saying is that a discussion should be considered. If there isn't any improvement by the Coke 600 on Memorial Day weekend, then maybe the discussion should take place.
I trust Tony to make the correct decision. He hasn't gotten where he is by making bad decisions. He will do what is best for SHR, the team and himself.
