Yeah, I wish they would force people to "assign" players without options to the minors, resulting in most of them hitting waivers.
One thing I am curious about - does a MLB contract help sign a prospect, other than the extra 1m or so he might have because of the 327k salary for three years? If I offer a MLB contract with a 12m bonus, is he more likely to take it than a milb+STI with 13m bonus? If so, how much higher would the bonus have to be before the minor league deal is more attractive for him?
