Everything that we saw go wrong seems fixable. My biggest long term concerns are the shitty play of Hightower and Bentley, and the D line getting pushed around more than I would have expected.I just re-watched the game. I though that other than the fumble, Harris ran great. He often got yards when nothing was there. Mac made a ton of great throws, often under duress. The receivers were solid and the TEs were good.
Hard to not be really encouraged by what I saw. The penalties and fumbles and otherwise the offense looks like it could be very good.
