Cutler is a streaky QB--capable of playing lights out one game and then stinking the next. If he is on when playing the niners it will be a very good game.
GB may have had a down game against the niners for many reasons--including the 9er D, the 9er O, out of sync without their OC, overlooking the niners, etc.
One game--we'll know a lot more about this 9er team after three or four games. I believe (and hope) that they will be a dominant O and D--expect some scores like 40-3.
The line did OK for the first game but when they play teams with more than one quick pass rusher or trickier schemes how will they look? My hope is that they simplify the pass blocking and let players control their zone more one on one. If they can keep one area clean (middle, left or right) so Smith has an exit strategy, the O will really benefit.
If the coaches get too cute and start changing up what works...we will all complain!
