I think you are confused.
I will speak for myself.
I thought the line was horrible with Levi Brown and Brandon Keith as the OT's. With Bridges I thought it would be a little better, with him at RT.
In the offseason (free agency to be accurate) I wanted replacements for both OT's and thought there was opportunity to do so. The Cardinals did not do so.
Now with Levi Brown hurt, and Jeremy Bridges hurt, I still say our line is horrible, but I am certainly not going to say the line got VASTLY WORSE because Bridges and Brown are hurt, and we are putting Batiste, and Massie in their place.
Does that make me a person defending Batiste, Massie, and the whole line for being the best of the best ? No. It certainly does it.
I just see putting Batiste in for Brown a very small regression at the position, and putting Massie in for Bridges a very small progression at the position.
So Brown-Colledge-Sendlein-Snyder-Bridges = Batiste-Colledge-Sendlien-Snyder-Massie. And where we have seen Brown and Bridges full potential, we have yet to see the full potential of Massie or in a lesser case Batiste.
IMHO.
Except for one thing. Continuity. Instead of one new face on the offensive line in Snyder we now have 3. To me that is a huge difference.
