It isn't as much Bo Jackson the finished player that I am thinking of, but Bo Jackson the tool box.
Bo had insane speed. The legends of his home to first and his 40 yard times are crazy. 4.13 40 yard, and home to first rumored in something like 3.8.
Bo hit the ball further than just about anyone in his time, in a era when just about everyone else was juicing, and still not hitting them nearly as far. His raw power was off the charts. The ASG homer is historic.
Bo Jackson's arm was crazy. The clip of his gunning someone down at home from the DEEP OF, is still floating around out there.
Mix all of those together, and the similarities from there also include that Luis never got get quality baseball training until the last few years, so he came in RAW, with flashes of those tools just leaving jaws dropped.
For me THAT is where the Bo Jackson comp comes from.
