Let's recap...
Costa started out miserably last season.
Just awful for the first six games. But especially bad vs New England.
But we need to keep in mind that he was injured the first part of the season, plus he had arguably the worst guard pair in football working next to him in Nagy and Kosier.
As Costa entered the final 10, he gained his health and one of the guards, Nagy was replaced by Holland, who played reasonably well until he inturn was injured towards the end of the season.
If you disregard the first six games of the season, Costa would have ended up being ranked in the low 20's per PFF.
But including the first 6 games of the season, Costa was the 30th ranked center in the NFL (out of 35 being rated).
This season?
Well let's look at the negatives...
He spent the bulk of training camp on the sidelines due to a back sprain.
His arms aren't any longer.
Now what about the positives...
By many of the reports, Costa came into camp bigger/stronger than last season.
He's been a starter for a season, i.e. more experienced.
The little glimpse we had of the last game vs Miami showed some good things.
From outward appearances the guard play this year will be to some degree better than last year.
Where do I think Costa will end up?
I look for him to be the 20th ranked center in the NFL. Slightly below average. But much better than 30th.
Of course he'll have some issues vs the Giants, the whole offensive line will. The starters haven't played together in a game yet. And this is the Giants who have a very good defensive front. Yes there will be issues.
Will the offensive line be good enough vs the Giants to get a win?
We'll see.
To beat the Giants in New York isn't going to be easy.
