I think Gman means that the waiver requirement will discourage teams from protecting career minor leaguers before rollover and I agree that there will be a ton of 6yr FAs with OV ratings in the low 60s demanding $multimillion contracts and remaining unemployed.
I also agree that this should be fixed. While there may be a hundred real life AAA players who think they deserve major league contracts as 6 year FAs each year, none of them will hold out after camps open rather than look for the best AAA opportunity for the new year.
It is, however, possible that we will see a worldwide pandemic of waivers 24-48 hours before Rule5 Day each year, which would reduce the probability of losing any given career minor leaguer waived.
