Most men lead very busy lives.
There are many business, social and family matters and obligations to deal with. At the same time, the desire to once again play the game they grew up with and still love remains strong. These busy people simply do not have the time to involve themselves with the standard men's baseball league. Existing mens leagues play two or three times per week, require practices, and traditionally involve the player in some other activity such as securing field permits, securing and paying umpires, calling players, collecting fees, etc. The final aspect of current men's leagues is that they are ultra competitive.
