Considering their first 2 draft picks were CB's and they brought in a new Safety, I'd be concerned a bit regardless of what they were or weren't trying to do against a mediocre pass attack.
Actually, both Smith and Davis played very well. If anything they were the two best defensive backs playing last night, even better than Will Allen. Also, I noticed that the Fins were playing a LOT of Quarters, which inherently gives up the underneath. One thing I did notice is that all the DBs seemed to get beat by the slant an awful lot, which makes me believe they were expecting more outside and deep routes.
Here's my theory. The Fins are transitioning to a 3-4 Quarters zone blitz, which so far as I know hasn't been tried in the NFL before. I think the coaches were treating that game as a lab to test some stuff. I did notice some huge pressure last night, so obviously the blitz is getting there, it's just the coverage that needs to be tightened up. I'm just glad that kind of game happened in the pre-season and not in week 2 like last year.
Btw, you were as impressed with Stroughter as I was? The dude was tearing it up.
