The "plan" is obvious and would be the same for any team in a like position. Options are draft and/or sign the best choice of the FA's available. Of course this comes with the understanding that the team likely takes a step backwards, but it that really such a bad thing? Ultimately you need to find your future in the draft and yes, there is no guarantee, but it is really the only viable plan. No matter who I had as a starter I'd be taking a flyer on lower round QB every year
Taking a step back while resetting the core is much more preferable than being stuck in the loop of easy out in the playoffs.
Kansas City and the 49's both had a Dak as QB1. Didn't stop them from churning the position through the draft and it payed immediate dividends. Seattle ditched their SB winning, 3rd round draft pick for a journeyman FA and improved on their previous season.
This "what's the plan" talk just seems like a smoke screen born of weakness. There is no rock solid plan that guarantees success. Only two options to replace the position, which you keep leaning on until you land the guy.
