To me, they're ultimately measured in championships. Crazy or not, it's what 50 years of success has bred.
On a micro level, sure - that's a success, because this QB has never done that. But I'd rather see them open it up and have Pickett make major strides but fall short of the playoffs than weasel their way into the playoffs playing the brand of football they are now, which comes with a very distinct ceiling. If Pickett throws for 300 yards and has a quality QBR the next 8 games but they come up a game short of the playoffs, it's a better building block than playing Tomlin Ball and ultimately being someone's sacrificial lamb in the playoffs.
They're like a 6'3" kid dominating Single A WPIAL basketball while playing in the post. Sure, I guess you can beat Avella that way. But you'll never get to the next level being a 6'3" post player.
