There were troubles in the entire Offense and WR sure didn’t help for a good part of the year.
For me the Oline was the biggest problem. Rodgers thumb after that.
Rodgers has been known for his accuracy and problems from the thumb his WR’s were not given the type of throws we and they are use to seeing.
If it was just rookie WR’s making drops that’s one thing, through out the receiving group is a different deal.
