Good decision. I'm a firm believer that you can't know every nuance about a player until he is on your favorite team. Only then is the surrounding personnel obvious, plus the coaching, plus the situation, etc.
I thought I knew Suh very well until he showed up on the Dolphins. I quickly realized he had weaknesses I wasn't aware of, plus some idiosyncrasies, plus some strengths.
What was going on when the Cardinals played the 49ers last season? I don't remember. There are situational ups and downs all season in the NFL. I've been frustrated countless times on this site when someone will post a supposedly representative clip...meanwhile one team was in lull mode and sleepwalking through the game while the other team was in a situational high. Sons of Shula never grasped that type of thing and often misinterpreted matchups or coaching as cause when it was nothing but an extremely obvious situational tilt, influencing that player and everyone else around him
Here's a big picture reality to keep in mind: Josh Rosen was the 10th pick in the draft and Arizona traded up for him. That is more valuable than studying old clips. I would be less enthused about the move if let's say Rosen was taken 22nd and he fell to the team without a trade up.
I mentioned 4 or 5 months ago here that first round quarterbacks are so coveted that outside the first 3 picks the last quarterback taken in the first round without a trade up involved was Eli Manuel to the Bills. I noticed the mainstream media finally caught onto that trend a couple of days before the draft last week and publicized a similar version. Very interesting that both Daniel Jones and Dwayne Haskins broke the trend this year. Nobody cared enough about them enough to jump up and grab them.
I'd prefer to have the guy who was pursued 12 months ago. I'll take my chances. Remember that Ryan Tannehill likewise fell to us without a trade up. Every other team in the league was content to watch it happen. In fact, the 6 picks immediately above us all changed hands at some point. The league was in trade happy mode.
