Mike Singletary and the 49ers need to concentrate on the offensive line and the defensive backs in this off-season. For the 49ers to give up the most sacks in the NFL, Singletary needs to figure out what is going on. The Cardinal game seem to show the problem being on the right of the line. The Cardinals were in the backfield all night. Hill showed great mobility, but made a few mistakes.
The defensive backs were allowing catch after catch. I couldn't tell if it was because of the cover defense or if it was the backs themselves. There seemed to be a lot of gaps that had the Cardinal receivers open all night long.
I don't think the 49ers need to do anything at the QB position. As long as Hill starts, he should develop and make less mistakes. He plays well, but there was an extreme amount of presser on him and he apparently is not use to that.
49ers...concentrate on the O-line and take a look at your D-backs. I believe that is where the problems lay just by what I see.
