Of course GA's SUPPOSED to be better. But pre-season rankings aren't worth much in August and September. He was dropped in two of my leagues, a 10 team and a 9 team. He has what must be considered 'significant' health concerns and hasn't produced even when in the lineup. BA alone isn't cutting it.
Have you both pleaded your case to the league? I have found often that once both sides justify their positions, others in the league tend to back off of the veto.
Blessed are the cheesemakers.
