There is no Kirk Cousins on the move this offseason. With how valuable the quarterback position is, it is rare to find even average quarterbacks hit the market, let alone anyone a team would legitimately want to build around. This offseason falls back into that norm.
In the absence of any true "franchise" quarterbacks, the best available free-agent signal-callers should have some level of starting experience. If they are thrust into a starting role, these should not be green players who need time to develop their senses with the first-team offense. They ought to be ready for the challenge.
