I don't know if it is solely due to having better athletes, but the play of the DB's tonight just seemed different. Tighter coverage for the most part, closing on the ball really well, just more aggressive in general.
I am starting to come around to the idea that the coaches kept things extremely vanilla last year because of concerns over depth, and perceived lack of athletic ability/talent. It could well be that Smith's system works - IF you have the right athletes on the field, and I suspect the Gophers are simply a lot closer this year to having those athletes in place. Would still like to see a little more pressure from the front four, but you can't solve every problem overnight.
