By giving the commissioners the ability to change position eligibility, changes in each league will occur much quicker and be custom to each league. For example, Steph Curry is always placed as a PG/SG, when people in my league agree he should just be a PG. Conversely there are guards out there like Lillard, Lowry, Westbrook, Ty Lawson and many more that have never been given SG eligibility when in fact they have played as SG. Additionally there should be a system that if a manager believes a position eligibly change is needed (ex. taking PF away or adding PF to a player), a request can be sent where the commissioner can review their proposal. Yahoo! can still roll out its own position changes, this just gives leagues more customizability and freedom. We hope this change is implemented soon. Please up vote.
