Yeah, the O-Line isn't the biggest issue. They could improve significantly in run blocking but their pass blocking is pretty solid.
It's an overall offensive issue.
Now that we know Gordon had one foot out the door I expect these receivers to step up and be hungry. JG was definitely an issue in game 1. The RB's could be better and Chubb needs more reps. Tyrod stands out as getting a lot of the goat horns because he's so limited and makes the offense look like it's in quicksand. We knew this coming in. Anyone who thought he was going to become "good" because he has more weapons was delusional. He is what he is, mediocre.
People want to see Baker because we know he can make all of the throws and the vertical game will open up which should help the running game. TT can't make the throws that Baker does. Pick your poison, safe, vanilla offense/gotta win with defense/limited turnovers or potentially explosive offense but there will likely be mistakes/turnovers?
