1980 Oak Rickey hit .303/.420/.399 and Dwayne Murphy hit .274/.384/.380, combining for 126-41 in SB attempts. In '82 they went 156-50 in SB.
1985 Yankees had Rickey then Mattingly or Griffey or Randolph. Rickey was .314/.419/.516 and they got .286/.340/.486 from #2 or Mattingly hit .324/.371/.567 on the year, if you prefer, though his 274 PA in the second spot produced a 1.087 OPS.
'89 Oak Henderson and Lansford is pretty good, both over .800 OPS, 148 and 131 OPS+s, 89-21 in SB, 121 BB between them. Lansford begat Dave Henderson who's 126 OPS+ rivaled Lansfords 131 behind Rickey the year before.
'85 St Louis, Coleman and McGhee? That's the best I've found, in SB anyway. 166-41 between them.
Looking through Raines' leadoff mates I find him hitting 3rd fairly often of course. The same scenario made the Ty Cobb search go quicker as well. But in 1986 Raines had 70G leadoff, 75 batting 3rd. That would be the year he led the league in BA and OBP. .334/.413/.476, 54 XBH, 78BB/60K, going 70-9 in steals. Mitch Webster took over the 2 hole that year with a .290/.355/.431 line, League Leading 13 3B, 52 total XBH, 36-15 in SB to combine for 106-24. 57-78 BB/K so they combined for 135/138 BB/K. How about that?
