That doesn't seem very consistant to me. About the only thing he was consistant at was games played.

His OBP and OPS was nearly identical for 7 years straight. Fluctuation in WAR can be accounted for by competition from other players at his position in any given year.

I'd say for a major league baseball player, those are pretty consistent numbers.

His OPS ranged from .700 to .760 while his OBP was between .313 and .333. I'm not sure I would consider those to be nearly identical numbers for either. If you take out years 4 and 5, then the ranges are .745 to .760 and .319 to .333 which are much smaller, but that kind of kills the idea that he was so consistent over 7 straight years since years 4 and 5 tend to be the low numbers for almost all of his stats.

Fella's, I guess the challenge would be to come up with another player who is more consistently, and reliably predictable from season to season across multiple categories then either Frank Malzone or Kent Hrbek.

I also posted Khris Davis's numbers across a shorter 3 year time frame.

Numbers will vary. Statistics always do....unless you're Khris Davis and batting average I guess.

I find those differences pretty minor, considering it's a 7 year time frame we're talking about.

I'm sure Frank is open to see example stat lines from other players that are consistently....more consistent. ;)

Tony Perez seven year run (hits are a bit off but check the ribbies) - Probably a lot of players similar to this .
If Pitchers were included Warren Spahn was very consistent
