Almost totally OT, but interested in your thoughts (very indirect connection to Middlebrooks' above). I was thinking the other day about whether or not a it would make sense to do a monthly weighted average OPS+ rather than a season-long OPS+. Practically speaking it's probably a weighted average of the sOPS+ numbers from B-R when looking at monthly splits. The rationale would be:
- Pitchers seem to have an advantage earlier in the season (cold weather).
- Hitters, especially power hitters, seem to warm up with the weather.
- Batted balls reportedly carry further in humid weather.
- September callups can skew numbers.
Basically my thought was that a weighted average OPS+ would give a more accurate reading for how a player performed against his peers over the course of the season. It would be more important for guys who played only part of a season (e.g., Ellsbury, callups).
