I just finished a season in a 1970 prog and my SS, Mark Belanger, may posted one of the worst seasons ever for a full-time player.
In 585 PA'd he went .176/.262/.199 w/ 8 XBH (6 doubles, 1 triple and 1 hr) and a RC/27 of 1.99. He managed 54 BB and was 6/9 in SB.
Defensively, he had 25 errors, 0 plus plays and 8 minus.
My question is... if I had replaced him with, say, a D/D rated player, how good offensively would that replacement player have to be in order to be more valuable than 1970 Mark Belanger?
