That's what Dallas Cowboys owner Jerry Jones called this weekend's stunning victory over the defending Super Bowl champion Seattle Seahawks.
Jones considers this the signature win of Garrett - who took over control of the team midway through 2010 - tenure.
"The reason is because this game is a little bit like it's been for Jason," Jones explained. "There have been a lot of mistakes, a lot of disappointment, but he stayed the course and he's turned around and put a team together that can compete like this and believe in what he is.
"I like the fact that his staff is as responsive to Jason as they are. I really will tell you, this is a Jason Garrett win for Jerry Jones today."
Oh, Jerruh. Can't help but get his own name in there. Classic.
But, he's right. This was a statement victory for Garrett and a statement victory for the now 5-1 Cowboys - a team most had written off as DOA prior to the season.
A couple of off-seasons focused on rebuilding the offensive line and a defense that has managed to come together better than anyone thought possible have brought the Cowboys back into the conversation as one of the best teams in the league.
Jones - as happy as he seemed to be with the victory - claimed this wouldn't be the catalyst for a sudden late-night contract extension negotiation session.
"I'll tell you this, I've spent more money in happy situations than we could in our lifetimes spend," Jones responded. "We won't talk contracts tonight. There's nobody that doesn't understand that when Jason does good, I do good. I'm being like a proud father. I'm proud that we're enjoying his success with his head coaching effort, and he deserves it."
Garrett, who has gone 8-8 the last three seasons, is in the final year of his contract.
"I've certainly had all of the appreciation in the world for everything Jason is as a coach," Jones said. "His qualities as an individual, a human being, his ability to lead men, whether it be his staff or his coaches. But what we certainly wanted to see success on the kind of impressive scale that we saw it today. Certainly yes, this is probably Jason Garrett's finest hour as a Cowboy."
