Time for the JG haters to go ballistic.
Advanced stats consistently show JG is much better than people realize and the O-line was much worse. It's why all the pipe dreams of a miracle QB who overtakes JG for the job are just that. JG has many things he needs to work on to become an elite QB, but he was one of our best players last season.
And sure, JG needs to make "quicker decisions", but the reason you think this is because he's constantly under pressure in a very short amount of time. No one would think that if he had Georgia or Bama's O-line. It's not even really the best criticism of JG. IMO, where JG struggles most is throwing on the run. That's what he needs to work on the most, because he consistently underestimates how far the ball is going to fly when he throws on the run.
But overall, JG is the least of our problems. Fix the O-line. Fix the D-line. Add depth. Keep recruiting well. Develop players. Then we'll win. Unfortunately, I think we're probably at least a year away on the lines.
