"Nowadays" is modern MLB baseball -- less guys on base is a direct product of less contact and less hits. It's literally all or nothing, as home runs and strikeouts are at an all-time high. Last year's Red Sox, for instance, set team records in HRs and for eight batters with 100 or more whiffs.
It wasn't that long ago, in 2013, the Sox' world champs had only one 30 homer guy -- Big Papi -- but only three batters with 100 Ks. If you really go back in time to 1975, Jim Rice was the only hitter on the AL pennant winners with 100 Ks. He also led the club in longballs, with 22. But the '75ers were an exciting offensive unit, pacing the league in runs, hits, doubles, batting average and OPS.
