Handicapping MLB Win Totals

[slogger]

I was wondering if anybody had some insight on what data to consider when projecting total regular season wins for MLB teams.

Trends such as taking unders for popular teams (NYY, BOS, CHC, ATL)? Importance of hitting vs. pitching? Importance of avg. age of players?

I'm looking to develop a system whereby I am able to project a certain win total for each team and then use that projection to determine whether any available Win Totals are worth betting.
