If Anderson & Carter go in the top 5, as they should based on talent alone...
Then the choice is between Murphy, Wilson, Christian Gonzalez (if he's the best CB), or Bijan Robinson (again, based on talent alone).
So... how do we rank those 4?
And to answer your question: I think yes on the 3 QB's. But that still doesn't change the fact that Carter & Anderson are top 5 guys, and the others are the "best of the rest". If only two QB's are taken in the top 5, then there is still the choice of whoever falls to us.
But at least at this point, I highly doubt either of those two slip out of the top 5. On the other hand...:
If it's Carter, I'm with buddha and thinking Campbell/ Holmes and Co. will have taken him off the Lions Board if he doesn't love the game enough and won't even consider him... although maybe that means a trade down opportunity.
If it's Anderson... well, I have EXTREME difficulty in believing that he'll be the guy who falls, even if 3 QB's are in the top 5. But if it is him, well... no-brainer.
