I believe they are a better team, BUT need time to get use to a new system, both on the field and off. Football is a game of strategy and systems, both of which do not come together easily. Players, coaches, and management have to spend many games and even seasons together before they become a winning, successful, cohesive unit, again, on and off the field.
Tillman has already gone a long ways in cutting salary, to comply with the new salary cap system. He was left with a mess, and has done admirably cleaning it up.
I think if we get rid of him because our record is worse than last years we will have to start from scratch again, something I would not look forward to, starting a new season.
Tillman and Austin have to be given time to grow this team, and if they fail to succeed after 4 seasons (or so), I believe then a new regime should takeover.
