If Herbert is there at No.7 after the Chargers pick, I can see the Raiders or some other team moving up. So, it always depends upon the right guy that is available. No one thought Malik Hooker would be available at No.15 in 2017 (he was rated Top 10 if I remember right). No one thought Castanzo would be available at No.22 in 2011 (he was rated a Top 15 player). Things happen in the draft you don't anticipate. That is why one could see 32 GMs have possibly 20 different boards for the Top 15 players.
You are entitled to your opinion as we all are.
Nothing Jacoby has done makes me think he will have a good season. He took all the first team reps through training camp and preseason so he should have been ready. Unfortunately he looked like he did every season including college. He has not improved. His flaws are the same which leads me to believe he is what he is. A very good backup QB and a below average starter.
If he starts, I will be pulling for him and hoping I was wrong.
