In terms of records..... not many will overtake MLB records.
You gotta remember, they didn't play as many games in a season as MLB players. And its probably why they are so comfortable doing this now. Gibson's batting average will be the all time best, but cac's will always point to playing fewer games.
The most games he ever played in one season was 94 and on average it was like 50 or 60.
But if you take Gibsons stats and average them out over a 162 game season
42 HR's, 185 RBI's, .365 ave, .449 OBP, .690 slugging
