Shaub or Flacco ain't going anywhere. No chance. You'll get no above average QB play in FA.
You might be able to get a Hasselbeck type, you know, wily old vet on his last go round. I'm down with that ONLY if you're also drafting a QB#1. The old guy can help coach up the youngster if he's a good team guy.
I don't know if it'll be Geno or Barkley, I see pros and cons with either. I'll rejoice either way.
