I get it is a lot to give up and teams usually only do that for a QB, but unless they absolutely love 2 QB's equally (that aren't Lawrence) why move to 3 and why move to 3 now. The draft is weird and if they do want a QB he might go 2 or he might be available much later. It is just a very strange move to make now, which is why it might not actually be about a QB, especially when they win at an elite level with their still relatively young QB.
