If you look at last year Chris Sale was the only pitcher to average 7 IP per game started. The game has definitely changed for the starting pitcher IP no longer really matters in terms of what constitutes an Ace, #1, #2, etc. With your first set of stats your #1 guy who gets about 33 starts per year barely gets to the 6 IP mark. That 6 IP mark on average is basically what teams are looking for their starters to go with the way the bullpens are put together and how they are used.
