It's not just championships, though that is a big part.Championships as a Player and Coach
Dabo - 2
Jim Harbaugh - 0
Also - Dabo is younger.
Swinney's teams regularly come up huge in big games. Harbaugh's teams regularly choke in the biggest moments.
Teams take on the personality of their coaches.
Swinney projects confidence and belief, and his teams feed off of it.
Harbaugh is a whining asshole whose sphincter tightens when the going gets tough. And then he goes ballistic on the refs, on his players, on the media... on anyone he can... in order to blame the loss on anybody but himself.
They both win lots of games.... but Swinner is a "winner". Harbaugh is a "choker".
