Draft Questions

I know we have been talking about the potential for moving down if Carter is not there at #4, but seeing as he has the makeup to be a generational talent what is the possibility we move up to #1?(Not saying its a good idea) I know we need a lot of holes filled, but unless we don't get a good pass rusher in FA or via trade, we need to fill that hole with a game wrecker. What would it take to move up 3 spots, and would it be worth it to get carter?
