Though I don't think we are in as horrible shape as some purport, but let's be honest with ourselves.
Tua being one of the least sacked had more to do with getting the ball out fast, rather than stellar line play. Using that as a positive is disingenuous at best because if we don't give the QB time to let route combos develope and go through his progressions, the better defenses that most playoff caliber teams have will be able to render us ineffective. Sure, we will still hit a big play now and then, but we will also have extended periods where we can't sustain methodical drives.
Being able to read pre snap and let the ball go on time with accuracy when he hits the back step of his drop is great until it isn't. When defenses can disrupt that by crashing down into the void areas, or jam guys at the line with physicality, we need to expand what we do. Those are perfect opportunities to make defenses pay for the over aggressiveness. You can only do that by holding the ball long enough for receivers to uncover.
