What's a "Franchise QB" really mean anyways? Does it need to be a rookie you draft? Someone who spends 5 seasons as your starter? 10? Does he have to be a Top 5 QB? Top 10?
I think it's obviously very important to have a top QB, but sometimes that "franchise" word gives totally unrealistic standards. If you're talking about a QB who is Top 5, spends 10 years on the team, and wins titles, those are 1 in 100 guys. If you're talking about a consistent guy who can play 5+ years for you, and be a top 10qb, then I can see Sam being that guy. Guys like Carr, Mariota, Winston, Bridgewater, aren't going to necessarily fall into either one of those categories. Even with a top 10 pick, your chance of hitting a Russel Wilson is probably 1 in 3.
I'd rather a much stronger team around Sam then a much weaker team around Goff who may not even become what we have now. If you're hunting for a top 5 young qb, and are unwavering on that, then yes maybe this is the year. Or maybe next year. Or the year after. If you don't see Sam as being your potential starter for 5+ years then you don't sign him to a 2 year 18 mil contract. Let him walk, suck and win 5 games by starting Chase, and draft a QB top 3 next year like Insein suggests.
