Fair enough, he's the most successful, but that depends on how you define success.
Well we won't know how successful he ends up for some time obviously, but he did very well at Penn State and certainly has the Texans trending in the right direction. Will he win a SB there....who knows?
And I edited in Saban since you said "elsewhere" but didn't specify the NFL.
Saban was Belichick's D coordinator for 4 years and has gone on to a little success in Alabama.
