If Phiilips was, say, age 25, a score of 24 wouldn't be that bad. At age 31 later this month, that is a score that says it is very unlikely he will make the HOF.
George Anderson posted Phillips's comparable players at age 30, his last full season, and noted that only Joe Gordon, with a comp score of 906, made the HOF. Jeff Kent had a comp score of 907 and may make the HOF, but Kent had just started racking up big numbers at that point in his career. For Phillips to make the HOF he will probably have to indeed put together another six seasons like his last six to have any chance, and it is unlikely that he will maintain that standard as he ages.
