To answer your question, yes, I like that guys like Cobb and Crawford are power hitters in PT. They were regarded as sluggers in their era and they certainly would have hit for power in 2011. Frank Baker would have more lived up to his nickname had he played in an era with a more lively ball, so yeah, I think itīs cool.
Of course there are some anomalies, such as when Tommy Leach led the league in HRs but all six were inside the park. Leach has a high power rating in PT which doesnīt reflect his true ability, but whoīs to say that the homers he hits in the game arenīt inside the park?
In fact your list leads off with an anomaly, Ned Williamsonīs 1884 season. Iīm sure you are aware that 1884 was the only year a ball hit over the right field fence in Lakefront Park was a homer. Because of itīs incredibly short porch (200 feet iirc), every other year balls hit over that fence were ground rule doubles.
So for me thereīs so many contradicting factors that I have no problem with sluggers being sluggers no matter what the era.
Now donīt get me started on the atrociously inaccurate fielding ratings, those I have a real problem with.
