1. In Al Golden's fourth year, there's enough talent, enough depth and enough time in his system that some of the ideas should be catching on. The strengths are there to win. They have running back Duke Johnson and a good offensive line. They have so many receivers a NFL scout said several will be playing on Sundays. They have a secondary that was good in coverage last year and added a contagious aggressive gene with Dallas Crawford moving to safety this season. But .... the overall defense remains the fundamental question of this team. It ranked 89th last year. It'll improve this year with nine starters returning. The question is how much? This season shouldn't be about Brad Kaaya, a true freshman at quarterback. It should be about the 20 starters returning to take some pressure off him.
