Normally, I am commish my own leagues, and I do this b/c I always enact my own settings. I always, for every league & every sport, have no waivers & no trade protests. Now, some of you may say that is crazy, people might cheat, blah, blah, blah... In my experience in reg. leagues w/ trade vetoes & waivers, crazy stuff happens anyways. Stuff like--very doable trades vetoed basically b/c bad teams are hatin on good teams (like mine). Seriously, this has happened 3 times to me already this year--last one Howard & Upton (to me)>>DeeLee & Kinsler (to them). It didn't stop there, recently, I put a waiver request on a couple diff' players last year and lost out to managers that rarely even check their team.
This is the last league I play in w/ waivers & trade protests. Some of you might say how does this work for you. I usually get 5-6 of my friends from other leagues that have experience w/ it, and the rest usually adapt, and end up liking it better.
