I don't know if the Giants and Steelers will take a QB in the first. But Milton may be looking at it like Wilson will be the Giants' starter this year and Rodgers when signed will be the Steelers' starter. Here, Dak is the starter, but he's coming off an injury that could keep him off the field, and he's missed a lot of games in the last five seasons (playing just two full seasons).
Why compete in Pittsburgh with a starter they just signed (if they get Rodgers) and a probable early draft pick (as the primary backup/starter in waiting) when you can go to Dallas with a starter showing signs of breaking down and no primary backup? Same with New York.
Both Wilson and Rodgers are on their last legs, but if I was Milton, I would think those teams plan to draft an heir apparent. I wouldn't think Dallas is because of its commitment contractwise to Dak. I'd think I'd have a very good chance of stepping in if he suffers an injury setback.
