text: what would ken griffey jr estimated home run total be right now had he not ever been injured?   all right, i'm not going to look at what he has done so far this season.... because it's just easier to figure out that way.    he's played in 2125 games, which would amount to about 14 seasons if he were to play 155 games each year.  he's actually in his 18th season, so you got to figure he's basically missed three years of playing time (remember, i'm not counting this season, so he's played 17 complete seasons).    his home run total coming into the season was 536, which over 14 seasons of playing time averages out to 38 home runs per year.  if you take that average over the three seasons that he missed, it would come out to 114.  so, theoretically, he should have been at about 650 coming into this season, which with his 12 so far this year would put him at 662, and on pace for about 688 by the end of this season.    however, he was at 398 before coming to cincinnati.  in his last four years in seattle, he was averaging 52 per season.  he's in cincy for his 7th season this year.  if he doesn't get injured and even averages 45 hr/season, he'd be looking at 713 at the end of this season.  as if this isn't way too much already, another way of looking at it -  he has averaged 3.7 ab/g, and a 14.68 hrr (home run ratio - the number of ab's between each hr).  if he played 155 games per season, he would have 2635 games, and 9750 ab's, which would translate into 664 hr's at the beginning of this season, and 703 at the end of this season.
