That's where it's hard to tell if he's truly modest, fake modest or just covering his a$$. I think he see's how many people blame Haney for Tiger's problems on the course towards the end of their relationship and is concerned if Tiger doesn't beat Jack, he could be tainted like Haney. If you say I'm "just" his coach, he's the genius, it appears as though he's not responsible for the good or the bad results which is a calculated risk.
I also thought it was interesting he has been working with Hunter the longest but spoke about him the least. I don't know if that was because Charlie Rose didn't show interest in Hunter or an indication of some problems between the two.
As to Hunter, that's the student that is not really progressing -- but it's Hunter's short game, I believe, that is holding him back.
Tiger is not really progressing - he did well at the beginning of the year, had the one tourney in the summer, and was majorly bad on major weekends with inconsistency.
I think Sean is covering himself to an extent.
