A win is a win, so 4-0 is good to go. 

I feel like the offense is forcing the long ball too much, and not using screens or mid-depth throws to open up the field for the run game.

It seemed like a lot of the time today, the WRs didn't have separation, and passes were batted away or intercepted. If it isn't working, adapt.

I'd give the offense a C and the defense a B in today's game.
