Hmmm lots of questions here. First question, as always, is sample size. How far into your season are you? It's possible these guys could underperform in the first fifty games or so. Less likely - you would expect "regression to the mean" - over a full season. Second, how do you play? Do you have player development on, and do you use a high (more than default 100 setting) for Talent Change Randomness, or TCR? Third, what kind of rotation do you have set up, and (related) what is your strategy setting for starters? It's possible (though unlikely, given the durability of SP in that era) that your pitchers are fatigued from overuse. Make sure you are using the late Seventies SP settings, and not the pansy-ass current day five IP and then the bullpen approach. Fourth, what are your overall stats, league-wide, for ERA, and for hitting? You could have a league-wide imbalance in favor of hitters over pitchers. In which case there are others who could help you probe "under the hood" for needed changes.
