You are cocky for thinking a coach can't teach you anything.
Anyway, like I said, either way it's just sad that you can't accept someone's knowledge and experience just because they personally may not have "won" or been the top of their field.
Charmichael may not have been as successful as a professional athlete as Lance, but he is clearly a very successful coach. Let's take Lance off the table, he's obviously not a coach so you don't get to pick him. Are you still saying that you don't respect the people I mentioned (to be fair Coggan is not a coach) because they have not personally won the tdf?
If Allen Lim offered you free personalized coaching, would you turn him down? No thanks man, I'm waiting for Lance?
