Brock averaged a 118 OPS+ for the 9 seasons from 1964 through 1972. That stat doesn't include SB value. Don't forget, his peak years corresponded with the era of overpowering pitching that resulted in the lowering of the pitcher's mound and the introduction of the DH.
But SOM's stat model doesn't really account for different eras very well, since their batter cards operate on the differential between the batter's stats and the league averages. Look at it this way.
In 1968 he had an OPS+ of 124, his OPS was .746. Dividing .746 by 1.24, the implied league average OPS was .602, and he was 144 OPS points above average.
In 2017, Corey Seager had an OPS+ of 125, with and OPS of .855. Dividing that by 1.25 gives an implied league OPS of .684; Seager was 171 OPS points above the league average. That, on a strat card, is equivalent to 18 singles above average for Seager, and only 15 singles above league average for Brock. Those 3 hits are worth about 600K in salary.
Of course that still doesn't make Brock an impact player, but another reason for that is the total devaluation of the stolen base in most leagues due to the heavy usage of power parks. And the third reason for that is that he wasn't really an impact player in his era, he just stole a lot of bases, legged out a lot of doubles, was a liability in LF, and ran the bases rather poorly.
Other regular LF's in the NL in 1964 included Billy Williams, Rico Carty, Tommy Davis, and Tommy Harper. Also appearing there was a young Willie Stargell. Of course, Brock mostly played RF that year. His competition there included Aaron, Clemente, and Frank Robinson.
In 1968, the story is much the same. Brock actually led LF's in bWAR that year, but was the 5th overall outfielder, behind Aaron, Clemente, Mays, and Felipe Alou. And Billy Williams, Cleon Jones, Dick Allen, and Alex Johnson all had 3-5 WAR seasons (Brock checked in at 5.8.)
Bottom line, he was a good but not great player, and is in the HOF for his counting stats, especially his 3000 hits and 900 SB's. His BBREF fielding advanced stats are not kind, with a net -51 runs. He had several years of +8 or +9 early in his career, but from 1970-1972 he was never better than -10.
