Look at the number of 20 game winners on this list not to mention a bunch of 19 game winners. These guys were not pampered with pitch counts back then and everyone on that list had a lengthy career despite that.
That is also the season that Steve Carlton won 27 despite the Phillies only winning 50 something games. That was a truly awesome accomplishment showing how great that guy really was.
1972 was a horrible year for Philadelphia sports. Besides the Phillies, I'm pretty sure this is the same year (72-73) that the 76ers went 9-73 which was the worst record in NBA history until the Charlotte Bobcats "broke" it. I don't think the Eagles had turned the corner yet as that was a couple of seasons later. At least I think the Flyers were pretty good but could be corrected on that.
Yes, 1972/73 saw the Flyers lose to the Canadiens in the Semi-finals. That same year saw them begin a playoff streak that would last until 1988/89! Go Flyers!
