It is also easier and less tiring for an OL to run block than pass block.
The challenge is that while easier, it creates a lack of urgency that puts you behind later. Expecting to come back, demands your defense hold the other team from scoring WHILE you come back. We don't have a defense to do this anymore.
Pete might feel that with a patchwork OL, this is his only recourse. But then, why the long developing pass plays?
Ultimately, this is more just his preference. He has a philosophy and for the most, it works for him. There is no reason to start fast because he rarely needs it. But it also makes it hard on us.
I've started rooting for us to be behind at the half, just so we start passing more and getting more urgency to score in the 2nd half. It is not generally good for us to have the lead at the half, it leads to a 3rd quarter much like the 1st 2 quarters.
We start slow because scoring in the 1st half isn't a priority for him. The goal for most teams is to score TDs in each opportunity. Pete has a goal of establishing the run, draining the clock, and trying to wait for the 3th+4th to start catching back up.
If we start getting behind, we speed up and score in the 1st half to at least get close. But that stops working in the playoffs, yet we are used to it - so we stick with what we know. Resulting in the other team scoring while we remain content to try to run down our own clock, thinking we can catch up later like we always do against lesser teams.
