I like Tony, I hope this isn't taken as jab.
But Tony seems to be more of streak type of performer. He has his slumps, and he some periods were he has some incredible runs and seems unbeatable.
I will not pretend to know the causes, but I have seen it with both Zippy and Grubb. I tend to think that's more a Tony thing, than a CC thing.
I can see Zippy with Joey losing a little enthusiasm, if I was JGR I would move him over to the 18 car. There you have a super fast driver maybe in raw terms the fastest, but still lacking the consistency of Hamlin's car (I realize this year is an exception thus far). Especially in the final 10 chase races.
Zippy has two titles, and should command Kyle's respect. Kyle's points verses his speed performance is the one thing he needs to master.
I would pair Logano up with a talented young CC, and tell him no more Daddy/Son relationship, to step and be the man of the team. Time to grow up and show us you are as good as we thought you were. It's make or break.
Back to Tony, just wait for the next hot streak, it can happen with Grubb or Zippy.
I also think the owner/driver hat is to heavy, and that's the greater catalyst.
Alan Kulwicki's accomplishment was a one in a go-zillion moment, and just about an impossibility to repeat.
