Oh, I am not saying that Mike should get Ray's job, but he certainly has been a bigger factor in the D than Ray so far. As for Ray's coverage ability...well, lets just say that I will reserve judgement until the games count, but so far Ray has been getting beaten BADLY so far.
Better than Ray? I'll wait on that one. Yes, I like the fact he's younger and busting through the line and crushing dudes in the backfield, but what would Ray do in the same situation? Also, while it is impressive Smith can time the QB's cadence, can he shed and tackle and can he cover like Ray? I hate to compare Smith to Nate Bolling but remember this is preseason.
I am not sure who you were watching, but Ngata was detroying his guy most of the night. Our run D was solid and CT was getting pounded at the line. On the other hand Brad Johnson was lighting our secondary up and I am very concerned by our DB play the last few weeks.
As for Ngata, I don't expect sacks, I just expect him to go forward and control his man. It wasn't happening.
