To get rookies on the right teams automatically from 1871 would require a lot of work, yes. The basic thing is the team Lahman ID needs changing - there are a lot of players who will attempt to import to teams which only existed for1, 2, 3 years... I don't know about other people, but I generally don't attempt to get the exact history from 1871-1900, so I let rookies be drafted. It's much easier from 1901, as there are just 2 team ID changes needed (a few more nicknames) in 1902 and 1903, all the way through to the 50s.
