Depends on if the giants are still in the playoff race in a few weeks. I havent watched much of Josh Jacob’s but if he’s an upgrade hes a better option. Expiring contract, 0-3 team currently, lower salary, might cost less in a trade.
That FG is automatic for most kickers so the numbers have already accounted for that. Your argument is actually hurting your position because the analytics don't know the Bills offense and Josh are the ones going for it. It's safe to say they are an above average offense.
Then there's the issue of making a FG and gaining a six point lead is actually worse, because now the dolphins have to go for it on 4th down and the win.
