If Joey Bosa is serious about this, then as soon as possible SF should be on the phone with LAC (why does that abbreviation always denote the team people care about least in LA?) seeing what piece they'd need alongside Dee Ford in a trade. If they know he doesn't want to stay, they might as well get something for him, and getting another edge rusher would at least be helpful to them. Wonder what else would need to be moved to make it happen.
That being said, I'm generally against such a thing. Be good for the team with the sibling rivalry thing, but it might also close them off into their own cliques and could upset the defense's cohesion. Meh. More interested to see how the team looks on Sunday with Ford back and rushing Rodgers
