Exactly.
Though the 4-1 start is great, the games showed how difficult it would be to win consistently when there are no off days for 15-20 days, the starting pitchers are only covering 5 innings (or less), and the offense only scores 3 runs. The strain on the bullpen trying to protect small leads would be unsustainable.
Tomorrow starts a stretch of 41 scheduled games in 43 days. For the team to be successful in that stretch the offense is going to have to carry more of the load than it has in the first five games.
