$100k seems cheap, but in modern Rule 5, you're not buying much. Take a look at the recent results: https://en.m.wikipedia.org/wiki/Rule_5_draft_results The last couple years, it's like maybe 1 useful guy out of 18 picks. By comparison, there are quite a few far more successful/valuable guys signed on minor league deals every year -- like Brandon Morrow for the Dodgers a couple years ago, Kintzler for the Twins, etc. Dereck Rodriguez, even. And those guys actually cost LESS than $100k (not to mention not requiring a 25 man roster spot). You'd probably be better off trying to identify those guys and enticing them to sign with the roster spot you would have used on a Rule 5 pick instead. It comes down to, what's the best 40-man I can assemble in the offseason? And what's the best 25-man I can field to start the season? Talent can be scarce, but not so scarce that Rule 5 picks need to be part of those roster equations, at the low odds of recent Rule 5 results. There's enough potential/talent available, in free agency, trades, etc., that it's easy to see why it's preferable for most teams to opt against drafting/rostering Rule 5 guys.
