I do believe that taking a PG year to mature academically and ready yourself for a school is very different from reclassifying in 8th grade or red-shirting in Kindergarten.
Many of the older players who took Post Grad years did so because they needed to as a contingency for acceptence to Lax U which would not of admitted them without lacrosse and without the PG.
I think this is a reasonable decision for an adult (18 yr old) to make and therefore very different from reclassifying and/or red-shirting in kindergarten.
In the post grad case there is no age based physical advantage gained during the recruiting period (no lacrosse cheating).
I am strongly opposed to reclassifying 13 year olds and red-shirting 5 yr olds, but if my son has an opportunity to attend a top school available only with a willingness to PG then I will support.
For your old school lax heroes you should check date of birth vs. HS graduation date. If you agree with me, perhaps you will start respecting some of them again
