The phrase "Mutual Admiration Society" goes way back, well before the staccato Broadway number emerged in popular culture in the mid-Fifties in the play "Happy Hunting" and in top-40 recordings. That's because the phrase so accurately captures the camaraderie between two or more entities, be they countries, teams or pitch-and-catch teammates.

The latest duo on the Jets to qualify for that sobriquet could be recent trade-acquisition wideout Adonai Mitchell and rookie quarterback Brady Cook.

"Yeah, it's growing," Cook, getting his second start and third extended game action as the Jets signal-caller at New Orleans on Sunday, said of his and Mitchell's chemistry. "He works really, really hard, and I've been impressed by just how he's supported me and how he's constantly in my ear since the Miami game."

Mitchell, when asked by nyjets.com reporter Caroline Hendershot which new mate has impressed him the most, replied: "It's hard not to say Brady. How he's handled himself these past two weeks with the ups and downs, it kind of feels like he's been here before."

Cook has also gotten some completions to John Metchie III, Isaiah Williams and, against Miami, TE Mason Taylor .. But Mitchell has been a go-to guy in the QB's short tenure as a starter.

Maybe it was Mitchell's one catch vs. the Dolphins. It was a downfield 24-yarder late in the game, certainly not a game-changer in the loss but still the first 20-yard completion of Cook's career.

Or was it his availability at Jacksonville? Mitchell was targeted a Jets-leading 9 times and had 6 catches for a team-high 58 yards and a touchdown. In fact, the TD, the first of Brady's pro career and Mitchell's second in three games, was the wideout's first target of the game. He artfully snagged Cook's 9-yard throw, a little high and a little hot, in the end zone to cut the Jaguars' early lead to 14-7.

Then there was the game ball retrieval. The Jets headed to the sideline for a brief celebration of Cook's first pro TD pass, but suddenly No. 15 broke from the Jets bench area back to the end zone to get the TD ball back from the EverBank Stadium ball wrangler and return with it to the sideline for his QB's trophy case.

"I did, I forgot about the ball," Cook said after the game. "Shoutout to AD. That's the type of guy he is. He's selfless. He was looking out for me, and the ball is safe, so I thank AD for that one."

Cook won't be playing favorites as he seeks the first winning start of his career under the Caesars Superdome. But he knows that if the Jets can run the ball against New Orleans' 26th-ranked run defense, that will create opportunities for Mitchell and the receivers against the Saints' pass defense, led by CB Kool-Aid McKinstry's 3 INTs and 10 PDs.

"It'll be a fun matchup," said Mitchell, who's played against McKinstry several times in recent years, "but I'm looking forward to going against whoever they put out there."

And that's in part because of the chemistry and, well, mutual admiration he and his QB have quickly developed.

"Just Brady's transition and how composed he is, how confident he is," Mitchell said, "I feel like it's contagious."
