Assume you were the manager and agreed. In the first month that pitcher could actually start 8 games. 40-42 starts? (Robin Roberts averaged 39 starts 50-56?) Extrapolating on former schedules a five? man rotation with one pitcher every four games (based on nor rain-outs) the fifth starter could have 8 to 101 games between starts.

lots of team chemistry issues but not including them, just creating a pitching rotation would be a challenge
