Two things I think:
1. The Raiders would not pass up Chris Long if he fell to the fourth overall pick. I can't imagine them passing up Howie's son, especially when they could use the talent at defensive end.
2. As much as they covet him, the Chiefs won't trade up for Jake Long. They have so many needs and so much roster turnover, they need every pick they can get.
Pugnacity, testosterone, truculence, and belligerence.
