I like the fact that Garrett is focusing on updating the process: higher tempo, practicing in pads, working earlier, better communication, attention to detail, etc.
We will see how the difference in process affects player execution.
A lot of people have blamed Garrett for the play-calling (including myself), but I would be interested to know how much of the failure fell upon player execution. With Garrett as a head coach implementing his policy, we have one variable not changing - his play calling - but several other variables changing.
I guess we'll see how much of a difference it makes come Sunday.
