How a team finishes makes a world of difference in terms of perception. Last year, the Phillies lost 96 games but played well at the end of the season (16-13 from September 1 onward and 12-7 in their final 19 games, including taking 3 out of 4 against a Dodger team that came one game short of the WC). Hence, I am sure that a common sentiment on September 30 will be "I felt a lot better about the future of this team a year ago than I do now." Is that sentiment realistic and fair?
One can point to 1995 and 1999 and see how late-season swoons foreshadowed dismal seasons the following year. But, at the same time, one can point to 1974 in which an up and coming Phillies team contended for much of the season but fizzled toward the end to finish 80-82, though that team only peaked out at five games over .500. That proved to be the prelude to the First Golden Age.
Strangely, it appears that the Phillies need to do what many thought the Sixers needed to do. Insert a superstar (or superstars) into a cast of supporting actors they developed. Embiid and, maybe, Simmonds may become superstar players but the superstar cavalry did not come riding over the ridge this offseason. The previous golden ages developed their own superstars (Schmidt, Rollins, Utley, Howard). This one, so far, has not.
If the Phillies can right the ship enough over the last seventeen games to salvage a winning season, that could help the perception a bit.
