I just started one in 1919, currently at Opening Day of 1928. I have recalc off, development engine on. Ruth has been good (leading the league in HR since 1918), but not quite Ruthian. He has been bothered by niggling injuries the past few years. Nothing major, but enough to keep him to less than 130 games. In spring training of 1928 however he had a pretty serious concussion that will keep him out for 4-5 months. We'll see how he comes back after that.
Interestingly, Boston also drafted Gehrig. I was imagining Murder's Row setting up in Fenway. Not to be as Gehrig has not panned out. He was given a couple of chances to crack Boston's lineup, but he didn't do well. Contact rating dropped precipitously. He was released and signed by the White Stockings. Currently sitting on Chicago's reserve list.
