John Madden has a great expre sion when it comes to describing a team's weakne s. The r always refers to it as the "yeah, but" for a squad -- as in, "This team is well-coached, they have a good offense, but their 'yeah, but' is the secondary."It's vintage Madden. And it identifies the area where a team can get exposed.Three weeks into the 2014 season, we a se s the "yeah, but" for a series of NFL teams, Schein Nine style:1) Miami Dolphins' offensive identityWhat is doing, I will never know.There is no identity, seemingly no strategy on offense. The , in their first season with Bill Lazor at offensive coordinator, looked both inept and ill-prepared against a depleted team in , and DeAndre Jordan Jersey that's totally inexcusable. Playing at home, Miami was rudderle s. was dreadful, completing just 21 of his 43 pa ses for a putrid average of 4.77 yards per attempt. The game plan was baffling.And then Philbin made it worse.On both and , the third-year head coach refused to publicly commit to Tannehill as his starting quarterback for this week's . When you're facing these lowly , don't you want to pump up your struggling QB and fuel him with confidence for a "get well" matchup with a bad team? Apparently, Philbin didn't think so.On Wednesday, Tannehill named himself the starter and . Oh, good -- just what Miami needs.With the way this season has opened, it sure feels like the beginning of the end for both the coach and QB in Miami.2) Philadelphia Eagles' first-half playThis one truly baffles me. And it's not just a knee-jerk reaction; there's a body of work to consider. Yes, Philly is the first team in NFL history to win its first three games after facing a double-digit deficit in each, but why are the digging themselves such a hole in the first place? Is it the offensive line, littered with backups due to key injuries and ? Is it the inability to establish the run with ? Is it the up-tempo practices, as ?I can't imagine it's the opposing defenses, not when you're facing , and . I would wager a gue s that this will be corrected at some point soon. , and the are too good to Nate Sestina Jersey keep playing 30-minute games.3) San Francisco 49ers' second-half playThere are stats and there are stats. Some are overrated. Some are fairly rated. Some hit you between the eyes, like this one:The have now been outscored 52-3 in the second half.That's eye-popping. That's embarra sing., I hit on how amazing the have been to start the year. And 'Zona, which just , is legit. But the other side to the story is that San Francisco simply imploded again in the second half. The Niners had foolish penalties and mind-numbing mistakes -- plus, they inexplicably abandoned the run.You don't ever expect this from a -coached team. But it just keeps happening.4) New England Patriots' offensive lineBrandt: to worry aboutGil Brandt eyes nine who are in danger of mi sing out on the next installment of the annual all-star game. 's Taurean Prince Jersey New England pa sing attack is stuck in the mud. Now there's a sentence I never thought I would write!At the moment, the Pats (and ). There are many theories as to why this is the case. I subscribe to the notion that the offensive line is awful, which precludes Brady from getting into a flow. The future r is taking waaaay too many hits. If this keeps up, he won't last the season.5) Indianapolis Colts' offensive play-callingPep Hamilton needs to repeat after me: "I have ." Say it again.OK, so the offensive coordinator just allowed his extraordinarily gifted QB to go nuts in , but I still can't get over how Indy approached that final drive . With the game tied at 27 and 3:25 remaining, the got the ball, setting the table for another cla sic, game-winning drive from Luck. Or not. Hamilton proceeded to hand off to on first and second downs, setting up a third-and-5 that Andre Roberson Jersey Indy couldn't convert. Of course, Philly got the ball back and .Why, Pep, why? That's winning time; that's time. Call plays like you employ or . The offense -- the team -- should be all about No. 12.6) New Orleans Saints' defenseThis one also confuses me. In Year 1 under coordinator Rob Ryan last fall, the ' defense was surprisingly sensational, . Conventional wisdom said the unit would only get better in Year 2, especially after the free-agent acquisition of .Not the case.The ' absolutely carved up the , to the tune of 448 yards pa sing and three touchdowns. OK, so Ryan is a strong QB. But then the -led had their way with the unit , and rookie enjoyed some succe s . Right now, in pa s defense.While I have to believe Ryan's D will get better and New Orleans will win the NFC South, provides a huge test, as the hit the road to face and the suddenly hot .7) Denver Broncos' running gameWith no longer on the team, Denver can't run the football. The currently and have notched only one score on the ground.I still believe this is the best team in the AFC, but establishing the run is a big part of the ' upside. has to do a better job. That's the one "yeah, but" when a se sing the Rodions Kurucs Jersey ' chances at landing another berth.8) Cleveland Browns' wide receiversAnd I use the term "wide receivers" loosely. Do the really have any you can bank on? Sure, just enjoyed a back-from-the dead fortnight, notching a touchdown grab in each of the past two weeks. And has racked up 21 receptions on the young season. But do either of those guys keep opposing defensive coordinators up at night?Hoyer's undoubtedly done an outstanding job working with what he has, but until returns from , the will feature one of the most underwhelming receiver groups in football.9) Cincinnati Bengals' kicking gameHarrison: Power Rankings, Week 4After three weeks, three teams stand alone at 3-0 -- but only one can take the top spot in Elliot Harrison's Power Rankings. The undefeated look fantastic to start the year. They look like a complete team -- with one notable exception, at this point. has already mi sed four field goals. He mi sed four field goals all of last season.The AFC North is tough; tight games will occur. Thus, when the kicker takes the field, he needs to secure three points. And come playoff time, this is increasingly vital.On the plus side: At least I'm not laying down my usual rant ...Follow Adam Schein on Twitter .
