With the margin for error being 60/162 of a normal season, they really can't afford to mess around with the roster this year. Put your top team on the field and let it roll. For a team that is probably just outside of playoff range in a normal season, also take advantage of the fluke that with one long streak, you can actually play yourself into a playoff race, or out of it if it is a bad one. There isn't time to cover up for a bad month or two week stretch.
