Well, I my 1922 Senators went 80-82 in round 1 (and won a weak division), but that included a 16-30 record in 1-run games, plus they had to deal with those really strong 1925, 1926, 1927 teams that combined to win 298 games. This team essentially has the same roster and should have an easier time in round 2.
