To be fair, using their methodology, drafting a QB in the first round really doesn't help either. Only 7 out of 48 QBs drafted in the first round since 1994 lead their teams to the playoffs in their first year. Two of those were last year, Luck and RG3, which everyone is saying are once in a generation QBs. Otherwise, '08 is the only other standout year when both Ryan and Flacco led their teams to the playoffs.
Before folks start their bitchfest and give themselves an aneurysm, understand I am only using the apparent methodology used by the article. I'm not saying that first round QBs don't develop into franchise QBs (ie the Mannings); I'm just using the same criteria as the article when they say that trading for a QB doesn't really help. Using their criteria, drafting a QB in the first round doesn't really help either.
