On a different note, analyzing Jeff Weaver's stats.

For the year 2005 Weaver had a .740 overall OPS, with 56% of the batters faced vs. him being lefthanded, with those lefties having a 867 OPS vs him, as well as an ERA over 4.0

In my Real Time league, Weaver has only had to face lefties 43% of the time due to the occasional rest vs. teams with loads of lefties, as well as the makeup of my division and league.

Results:

3.36 ERA, overall OPS of .681. By being able to face more righties than lefties, he was able to use his 584 OPS vs righties more to his advantage than in real life, producing a very solid year.
