Kellen Moore is truly getting the last laugh here.

Despite being monumentally outplayed in the preseason by undrafted rookie quarterback Cooper Rush, the veteran has someone continued to convince the Dallas Cowboys he's the rightful backup to Dak Prescott. The team had finally shown signs of at least entertaining placing Rush at QB2 -- as evidenced in their final preseason battle against the Oakland Raiders -- followed by releasing Moore in their final roster cutdown.

He'd ultimately clear waivers, as they expected, and was re-signed to the club on Tuesday. And now, he's landed back where he started:

In the No. 2 position.

This move will see Rush relegated to the inactives list for Sunday night.

Despite what the numbers say, and they say a lot, the Cowboys are still sold on Moore for whatever reason.

“He’s a very smart player, makes good decisions,” said head coach Jason Garrett late in the preseason, via Fort Worth Star-Telegram. “I thought he threw the ball to the right guy a lot. I think the biggest thing if you look at his drives is we got behind the chains a little bit, had some holding penalties and you’re looking at some tough down-and-distances.

"And it’s hard to overcome that. But I thought he handled that stuff for the most part pretty well and just kept trying to execute ball plays. He will continue to do that.”

And then came the vote of confidence from owner Jerry Jones himself, whose praise of Rush stopped well short of handing him the keys to the QB2 role.

“I’m just glad to see Rush taking advantage of his opportunities out there,” Jones himself iterated to Fort Worth Star-Telegram. “Wouldn’t want to get ahead of ourselves in any way here. And the other thing is that we still have a lot of confidence in [Moore], his ability to be able to get in there when we would call on him with the personnel around him and get the ball in the right places.

“Make no mistake about it, that Rush, it just gets slow when he gets out there. That’s a compliment."

The bigger compliment would've been to grant him the QB2 spot, considering he's earned it.
