All this is well written and I'm sure you'll get a ton of people to agree with you, but I couldn't disagree more.
1. You are talking about admitting he's not top tier. Are you serious? Can you imagine how little respect he'd get from his teammates? If you're saying he needs to put in more work to be as good as he wants to be than great, but "admit to himself he's not top tier" why even play the game if you don't think you are as good as the next man? Also let's not make Brady out to be such a great team guy. The Patriots came to him and ask him to restructure his deal, but he was always paid the same amount of money in the end. He didn't "give up any salary" No different than Flacco restructuring his contract this year, which he didn't have to do btw. Flacco's exact words.
Futhermore, Flacco saving the Ravens cap money allowed them to make a competitive offer to KO but the deal he signed just wasn't smart for the Ravens, especially if he wasn't gonna be a LT. Since signing Flacco to the huge deal, the Ravens have signed, Yanda(15'), Monroe(14'), Weddle(16') Wallace(16') Watson(16') Jimmy(15'), SSS(14') Zuttah(15'). None of these players were fall back options for the Ravens. They were guys the Ravens wanted, so who exactly how has Flacco handicapped the Ravens? QYeah they weren't able to sign KO and Torrey but it wasn't because of Flacco's contract. Now of course Flacco's cap number has some impact on the team's ability to shell big money to some guys, simple because you can't sign everyone but i'm sure much like Brady if the Ravens approach Flacco about getting most of his salary in bonus money to save cap he would because it costs him nothing.
3. Just doesn't make sense to me. Your QB has to have input in the offense. Furthermore, the only time the offense seemed to really click is when Flacco was running things at the LOS. So why wouldn't you just go into the offense focused on him mastering Marty's system and working with his young WRs/TEs to get everyone on the same page as much as possible before offseason workouts. Also, by all reports that i've seen on the matter Marty is exactly the type of coach you described. He's a no nosense type of guy that isn't afraid to get in his QBs or HCs face to get his point across.
4. Are you kidding me? Seriously? I know Flacco had a down season and he'll probably get beat up all offseason until he performs well next season, but you can't be serious with this. Address his ego? What NFL player doesn't have a ego? I'll tell you the guy that isn't any good, that guy that's just happy to make the PS squad is a guy that doesn't have a ego. Did you hear what Aiken about knowing he's a starter in the NFL? Did you read the reports or see the reactions of Wallace and SSS when they wanted the ball? Have you ever heard Ray Lewis or Ed Reed speak? His ego is out of hand because he didn't want to be a wildcat QB? Really? Not to mention that was a full 7 years ago. Again what professional would not think they are the best, even if they know the next man is better? How would you really react if Flacco went into a big game vs Brady or Ben and said. Yeah I know i'll never be able to go out and have my offenses play to the level that those guys well, I just hope they make a few mistakes, so we can keep the game competitive lol. I'm sorry but i want every single one of my players thinking they are the best at their position and giving their teammates that confidence as well.
