I don't understand why fans think this has to be a "multiple year/3 year process" type of thing. Things turn around so quickly in the NFL. If we play well, take care of the ball, cause turnovers, and get some bounces, it's very plausible to go 9-7.
It's done so often now. Every year there is a team(s) that surprises everyone. A few that come to mind the Browns, Jets, Saints, Bears, Giants, Titans, etc. All were expected to lose, not make the playoffs, etc. and all had fine seasons.
Phil played for Parcells and knows his track record for turning around franchises.
