For me,
Rec. ball had its place. (Yes...drunken, washed up, wanna-be men basketball players for the most part.)
I should know...I played men's rec ball for 19 years.
(and still play noontime ball at the club when I have days off.)
Anyway, Rec. ball does have its place for some officials, IMO. Just starting out as an official, it gave me actual game situations. It gave me game time. I got to blow my whistle without the pressures of a whole bunch of fans in the stands. I got to practice mechanics, switches, rotations, and maybe most of all...game management.
I used Rec. Leagues to work on getting better...it was a training ground of sorts. After about 8 years of that stuff, it wasn't any fun anymore...it wasn't serving a purpose...I wasn't practicing mechanics anymore, in fact I was getting lazy, getting a bad attitude and developing bad habits. Simple solution, get out.
So, Rec. Ball does have its place...its just a place I don't choose to go at this time.
