I'm withholding judgement until we see what changes are made to the racing itself (if any). I dislike the Chase as much as the next guy, but realistically it hasn't changed the basic principle of the race winner being the driver who crosses the finish line first after the designated number of laps (give or take an overtime). As long as that stays the same, I'll be here. If not, there are always other forms of motorsports and entertainment.
For now, I'll welcome them, giving them the benefit of the doubt and an assumption of good intentions.
