Well no, but having Carr doesn't stop you from looking for a franchise QB and you never know where you are going to find them. Sometimes it the first round or second round. Other times it's the 6th or 7th or free agency.
But Carr is a solid QB who is good enough if you have a good OL and a good defense. And if you have that, you are ready to go when you do find a better QB than Carr.
