Not all teams are built around one or two guys, Arizona last year didn't have a game wrecker like Mack or Miller, they just had a very consistent offense and a creative defense that thrived on turnovers.
Now, say we trade back in the first and maybe trade back up in the second, and we walk away with Charles Harris, Tre'davious White and Ethan Pocic, we have a dangerous roster. We have a mauling OL for our run game and an explosive and fast defense. We are 8-8 not because we are a bad team, but because we're in a transition. The only players that were here during the SB were Flacco and Yanda, so of course we need to start from scratch and Oz has done that very well since 2014 and given us plenty of talent to work with. Now it's just enjoying a draft class that is taylor made for our needs and finishing the rebuild we've had since Ray and Ed left.
