I'll explain that. BEFORE they created tryout camp position players, you had to fill out your minors by signing your draft picks. A 29 y/o who might be the 28th man on your roster isn't worth 1.5m a year. So, rather than continuing to bring back retreads for 1m to fill out your minors, you'd sign your draft picks. NOW that's unnecessary. Under the old system, if FA would drop their demands to minor league, worlds would eventually run out of position players because owners would keep bringing back that 30 y/o players for 54k(and keep him on the 40 man so he couldn't go FA again) until he became useless. At the cost of that, draft picks would go unsigned in order to save that 175k you'd pay for 6 position players for a single IFA.
I'm saddened by the fact that sometimes people just don't realize what they asked for and WifS doesn't recognize what they've given them.
