The sad part is a couple of people on our board actually LIKE this dopey idea.
Among other things it completely devalues the regular season where you have to sell 40-50000 tickets for 82 games a year, not 20000 tickets for 41 home games like the NBA or NHL. There's literally no chance the top four or five teams in each league will miss the playoffs and no real September urgency other than among the bubble teams and maybe the top two seeds to get the bye (which itself has questionable value in baseball).
That sense of urgency for fans of teams in the ~16-20 range leaguewide is not there in the current system. Even if this results in waning interest in the ~6-10 spots, this creates it down the standings.
I'm a casual baseball fan and I assume the league is targeting someone like myself with this. Watching the team I follow, the Pirates, in August and September in the decline phase of the competitive cycle has been dreadful. I want to care, but the entertainment value is poor. Under this system, they're in the hunt into the final weeks in 16, on the periphery in 17 and a playoff team in 18. I would have been more interested in getting to the ballpark, freezing my butt off from the whipping winds of the Allegheny River in September, and actively watching the team on TV if they had been more competitive. That would have bled into October too; I watched much more of the postseason 13-15 than I did 16-19.
