The other route is the 49er/Dolphins route. Somehow hit on draft picks and trades for high end offensive talent and get an average QB.
The issue with that, as 49ers and Dolphins are now finding out is instead of paying 2 top guys, 1 being a QB, you need to pay 4 or 5 guys top dollar and you just can't afford to keep them together for as many years as just 1 QB can be locked up. Your window is much smaller without a top 5 NFL QB
Unless you have the 49ers or Dolphins skill players, you need a good QB, not just solid.
Matt Cassell took a 16-0 team, lost 5 games and missed the playoffs.
In 2016 they got SHUT OUT at home to a weak Buffalo team, just because of Brissett playing QB with a top offense.
