OK, but you're making my points for me. How do you prepare to not execute? Like what's Roman supposed to do differently to get receivers to catch the ball? To get Guards to execute pass protection?
If you're acknowledging the playoffs are "different", than why are we trying to build an offense for games that a) we don't know if we'll even be playing in (see last year) and b) is primarily about execution?
I don't know that Roman's "offense" can win in the playoffs, because I haven't seen the Ravens team successfully execute what he wants to do in the playoffs.
You're also making my point about Belichick. What you just described is called building a team that's versatile and isn't pigeon-holed in winning one way. He can run the ball on anybody. When he had Brady, he could obviously throw it on anybody. He looked around the league about 5 years ago and realized "hey, everybody is building great secondaries and great pass rushes", so why is he going to bother trying to load up with high end outside receivers, when every defense in the league is largely trying to build a defense to stop that? So, he doesn't. He loads up on TEs who punish linebackers, RBs who can catch, and slot receivers. And he attacks the middle of the field where most defenses are weaker.
With Brady that worked wonderfully. Without, not so much, because they're not threatening anybody in the pass game at the moment.
Historically, he's also struggled to defend Lamar-style QBs. QBs who can run, and especially, who can run the option, have been giving Bill fits for years. That's mostly because in order to defend that, he needs a linebacking and Dline core that can, and he spends most of his defensive assets on the secondary, like most teams do, because its a pass-heavy league.
End of day, building an offensive scheme that's purely designed to "win in the playoffs", to me, is totally asinine. You should build an offense to be a good offense. Home, away, playoffs, regular season. Doesn't matter. If you don't win enough between Sept-Dec, doesn't matter what you do in January, because you won't be playing. I'm not interested in having an offense that's perfect to beat KC, but ends up making us a 9-8 team. Just because a style of offense can beat specific teams doesn't mean it can beat enough teams.
And while you're certainly not the only person doing this, its extremely "odd" to be praising Belichick for his game planning and schemes, when the Ravens are, in some ways, doing exactly what he's been doing for years. Why do you think the Ravens are emphasizing the running game, TEs, etc. on offense? Because most teams aren't built to stop it. I know a LOT of teams who have secondaries that can at least slow down elite offenses. I know a lot of teams that have great pass rushes and/or a really strong secondary.
I know very few who can consistently stop the run, and I know very few who are great in coverage against TEs and inside receivers.
So do we want the Ravens to attack what other teams do poorly, or do we want them to just be like the Chiefs, the Bills, etc., who have potent passing attacks with lots of speed and lots of deep shots, but can't run the ball consistently at all and become one dimensional frequently in a big games?
