Best lefty off all time? My vote is Koufax!

Yeah, I'm sure the guys Grove was striking out (as he led the league 7 straight years) said he was a pretty outstanding pitcher too. Are we supposed to stack up quotes from guys who faced Koufax but not Grove, vs guys who faced Grove but not Koufax, and try to figure out who piled on the superlatives to the greatest extent?

As far as Sandy and his Cy Young awards, Grove would've at least equaled, and probably topped him. Let's compare their top 6 season runs:

Grove
1928 24-8 2.58 (led in wins, strikeouts)
1929 20-6 2.81 (led in ERA, strikeouts)
1930 28-5 2.54 (led in wins, ERA, strikeouts)
1931 31-4 2.06 (led in wins, ERA, strikeouts)
1932 25-10 2.84 (led in ERA, strikeouts)
1933 24-8 3.20 (led in wins, strikeouts)

Plus 148 more career ML wins, and 111 minor league wins

Koufax
1961 18-13 3.52 (led in strikeouts)
1962 14-7 2.54 (led in ERA)
1963 25-5 1.88 (led in wins, ERA, strikeouts)
1964 19-5 1.74 (led in ERA)
1965 26-8 2.04 (led in wins, ERA, strikeouts)
1966 27-9 1.73 (led in wins, ERA, strikeouts)

Plus 36 more career ML wins

Grove's best season, 1931, beats Sandy's best (1963 or 1966, you choose)
Grove's best 6 year run beat Sandy's
The remainder of Grove's career destroys Sandy's (148 more wins to just 36)

For extra credit, Grove was forced to spend his first 5 years in the minors, where he won another 100+ games.
