I agree with others that the line is still trying to get some things figured out. They were starting to move people around yesterday and getting 4-5-6 yard chunks which was a welcome sight after the first few games. Hopefully once Schott is full-go things will continue to develop.
To OP's point, one thing BF will do that drives me nuts is call stretch plays to the short side of the field. Goodson clearly has big play ability if he can get out in space, so I'm not sure why we run plays where space is limited.
As for Petras, I don't think his ceiling is incredibly high, but at least his floor is going up. I'm as frustrated as anyone that he'll short hop a ball on a timing route or put the ball where the receiver can't do much with it, but to date he's not turning it over. When you have a weapon like Taylor and our defense, we don't need him to put up gaudy numbers. But it would be cool as hell if he did.
All in all, it's hard to be mad at 3-0 while still trying to figure things out and 2 wins over ranked teams in our pocket. I'll finish off with giving props to Terry Roberts. Normally a great special team guy, but showed out on defense and showed he belonged.
Tl;Dr - go hawks
