Total games played in 2010 is almost double that of 1960. Yes HRs are up from 1960 levels but you'll get a better historical trend line here.
There's more than twice as much talent available today than 50+ years ago that would mitigate that factor, not to mention the technological advances in sports medicine.
The league as a whole may play more games, but pitchers are obviously pitching much less. If it was simply that only the exceptional could face 1250 batters a year fifty years ago, we should still be seeing the elite pitchers throwing 300 odd innings a year.
edit: after more careful reading, perhaps this should have been posted in response to Voodoo's comment.
