Neither of you should apologize for prolonged success!
I've seen many owners over the years sit atop leagues winning multiple Titles including myself at one time.
It gives the other 31 owners a very lofty target to aim for and makes everyone elevate their own game if they want to knock you off your perch!!!
The one thing I know for 100% certainty is that every run, even 10 year runs comes to an end eventually!!!
