Respectfully disagree. Unless my aging eyes are failing me (a genuine possibility), I see missed tackles, man coverage that is beyond explanation, a QB under constant pressure and whose ability to throw the ball is clearly suspect. I don't mean to say that there is no talent out there. What I mean to say is there is a clear absence of fundamental football.
I was not at ANY of the practices, so I cannot say if these players came to us without fundamentals and were not taught, or (more likely) just are not performing. There may be culpability in coaching there, but I think it more likely that these players are simply not performing. Where there is clearly culpability in coaching is the stubborn insistence in sticking with things that are not working (press man comes to mind).
So, to respond directly: It IS the players, slick. But there is plenty of suck to go around and the coaches are in the mix too.
